Description

FIELD OF THE INVENTION

The invention relates to radio engineering and can be used in beacon systems (RMS) landing meter range of wavelengths of the format ILS (Instrument Landing System) for instrumental support of approach and landing of aircraft. Heading beacons (CRM) included in these systems form a heading zone designed to control the aircraft in a horizontal plane. CRM in accordance with the present invention allows for instrumental approach of aircraft for landing and landing of aircraft under adverse weather conditions for visual landing.

State of the art

The ILS KRM antenna system is installed on the continuation of the axial line of the runway (runway) at its end, opposite to its threshold from the side of the aircraft landing approach. The CRM antenna emits electromagnetic waves into the surrounding space in the frequency range 108-112 MHz, modulated in amplitude by the signals of the tonal frequencies f ₁ = 90 Hz, f ₂ = 150 Hz. In the ideal case, the surface on which the difference in modulation depths (RGM) by the signals f ₁ and f ₂ is equal to zero is a vertical plane passing through the axis of the runway (course surface). Under real conditions of the airfield, a certain surface of points is observed at which the RGM = 0, which deviates from the plane. During the operation of the first landing radar in the middle of the last century, a relationship was found between these deviations (accuracy characteristics of landing systems (SP)) and the size and location of local objects at the airport, such as the terminal building, hangars, aircraft parking lots, etc., as well as the shape terrain in the zone of entry of aircraft for landing. The cause of the curvature of the heading line was interference in the heading area of electromagnetic waves reflected from local objects, with electromagnetic waves forming the course surface. The ILS accuracy is subject to high requirements, which are an order of magnitude higher than those for aerodrome navigation and radar systems.

The natural desire of the RMS developers was to narrow the radiation patterns of the Raman antenna in the horizontal plane, in which local objects would be irradiated with a negligible level of Raman signals [Watts, S.V., Jr. Instrument Landing Scrapbook / C.V., Jr. Watts. - Trafford Publishing, 2005. - p. 165 (392 p.p.), NII-33 / VNIIRA. The history of the formation and development of the All-Union Scientific Research Institute of Radio Equipment - St. Petersburg: 2007. - 291 p.]. However, it is difficult for the pilot to get into a narrow zone. The International Civil Aviation Organization has established the minimum angular dimensions of the coverage area of the CRM system [Appendix 10 to the Convention on International Civil Aviation. Aviation telecommunications. Volume 1. Radio navigation aids. ICAO, Montreal (Canada), 2006. - 606 p.]: ± 35 ° in the azimuthal plane.

The problem of providing, on the one hand, high accuracy in setting the flight path by narrowing the antenna beam and, on the other hand, providing wide areas of Raman operation, was solved in beacons with a dual-frequency mode of operation. In this case, the so-called capture effect is used. The dual-frequency Raman mode involves the formation of two high-frequency signals: the main signal of the narrow channel (CC) and the additional signal of the wide channel (CC). The task of the UK is the formation of narrow angular zones: course zones within ± 2 ° relative to the runway axis. In these zones, a linear relationship is established between the value of the information parameter (RGM) and the angular deviation of the aircraft from a given trajectory. The wide channel provides the pilot with information in the rest of the coverage area, "indicating" the direction of the "correct" movement towards the descent trajectory. In this case, the carrier frequency of the CC signal is shifted relative to the frequency of the CC signal by 5-15 kHz.

By forming a special-purpose pattern, a significant excess of the level of CC signals is achieved in comparison with the level of HF signals within a narrow zone in the vicinity of the course line (± 2 ° relative to the runway axis) and a significant excess of the level of HF signals compared to the level of CC signals within the guidance zone.

The accuracy of the CRM is directly related to the characteristics of the patterns of their antennas. As is known, the shape of the antenna system’s DN is determined by the amplitude and phase distribution of the currents supplying this antenna system. The position in the space of the course line is sensitive to changes in the phase and amplitude distributions of the supply currents. So, for example, when the course line position on the opposite end of the runway changes by more than 3 m relative to it in one direction or another, the CRM equipment switches to the backup set. Therefore, along with high requirements for signal generation paths of the joint venture blocks, high demands are made on the accuracy of the joint venture parameter monitoring system.

Traditionally, to increase the reliability of CRM control, they use, firstly, the so-called "built-in control" performed by signals branched in the feeder path, and secondly, aperture control performed by CRM signals received by probes in the near zone of the antenna, and, thirdly, the remote control performed by the CRM signals in the intermediate zone of the AR (in the Fresnel zone).

The essential features of this technical proposal for the construction of CRM relate to an aperture control device for its output characteristics.

Known for the first two-frequency ASM, which is part of the landing system SP-70 [Sosnovsky A.A., Khaimovich I.A., Sholupov E.I. Radio beacon landing systems, Moscow, 1974].

The first RPC contains a first narrow channel (carrier LF CC) signal conditioning device (carrier plus side frequencies) (hereinafter, the first device), a second narrow channel (LF CC) signal conditioning device (hereinafter referred to as a second device), and a third shaping device carrier plus side frequencies of a wide channel (LFCC) (hereinafter, the third device), the fourth device for generating the signals of the wider side channel (WFCC) (hereinafter, the fourth device), the first switchgear (RU), the second distributor th device first linear antenna array (AR) of a narrow channel, the second linear AR broad channel, three sensor aperture control. The narrow channel signals through the first switchgear are fed to the first AR. The signals of the wide channel through the second switchgear are fed to the second AP. The narrow channel AR contains 18 radiating elements, near which there are 3 sensors, sometimes called measuring probes. Next we will use the term sensor.

The disadvantage of the first CRM is unreliable aperture control, because Only three of the 18 radiating elements of the AR are subjected to control.

A device for aperture control of the CRM, which works autonomously, without galvanic communication with other CRM devices [US 4,107,688 Andrew Alford. Monitor for localizer antenna arrays].

In said aperture control device, the number of sensors is equal to the number of radiating elements in the AR. The disadvantage of the aperture control device under consideration is the too complex device for summing the sensor signals. The complexity of the device is due to the need to ensure equal complex transmission coefficients from each sensor to the output of the terminal adder. In fact, the feeder path of the aperture control device exceeds the number of elements of the controlled path by the number of elements included in it. The complexity of setting up the aperture control device exceeds the complexity of setting up the distributor of CRM signals. Since the reliability of the device is inversely proportional to the number of elements in the device, it turns out that a reliable distribution device is controlled by a less reliable device - a device for summing sensor signals. The situation is aggravated by the implementation of the proposed principle in dual-frequency CRM. In the dual-frequency CRM, it is necessary to control, along with the control of the course line position ("0" RGM) and the slope of the zone along the narrow channel (S _ck ), another parameter - the slope of the zone over the wide channel (S _ck ).

Known for the third two-frequency KPM (SP-90, course beacon (RMK). Technical description ICRV.461512.019TO, NIIIT-RTS, 1996-1999).

The well-known third CRM contains a first narrow channel (carrier LF CC) signal conditioning device (carrier plus side frequencies) (hereinafter, the first device), a second narrow channel (frequency CC) signal generating device "side frequencies" (hereinafter, the second device), a third device a carrier-plus-side-frequency signal generation signal of a wide channel (LFCC) (hereinafter, the third device), a fourth wide-channel signal (lateral frequency) signal generation device (BH-CC) (hereinafter, the fourth device), switchgear (RU) with four inputs and 16 outputs, a linear antenna array (AR) of 16 radiating elements located symmetrically relative to the center of the AR, 16 sensors with drop cables, phasing cable sections, a signal adder, a modulation depth difference modulator (RGM), matched loads; while the sensors are located near the radiating elements of the AR.

A significant disadvantage of the known third CRM is the complexity of the adder.

The complexity of the above devices is due to the fact that their work is based on the principle of parallel summation of signals.

A device for generating signals of aperture control of the CRM is known [Application No. 2012119089/08 (028764)], in which the reception and summing of signals is performed by a coaxial waveguide with radiating slots, the wavelength of the received signals in which is equal to the pitch of the antenna array. In this case, a coaxial waveguide with radiating slots performs two functions: the function of sensors and the function of an adder. The implementation of these two functions is ensured by the choice of the step of the antenna array equal to the wavelength in the cable. This device eliminates the disadvantages of the aforementioned CRM, consisting in the extreme complexity of the summing device.

The disadvantage of the device according to the application No. 2012119089/08 (028764) is that it cannot be used in the case of non-equidistant AR. This narrows the scope of the specified device. It is known that the use of non-equidistant arrangement of radiating elements allows to optimize the characteristics of antenna arrays. Thus, the use of the nonequidistant arrangement of IE in the AR KRM SP-90 made it possible to reduce the number of IE in the array by 2 IE without deterioration of the parameters of the ASM in the zone of its action.

Turning to FIG. 1, a structural electrical diagram of a two-frequency directional radio beacon (CRM) in accordance with the present invention according to the first embodiment is shown.

The RPC contains a first narrow channel (carrier LF CC) signal conditioning device (carrier plus side frequencies) (hereinafter, the first device 1), a second narrow channel (LF CC) signal conditioning device (hereinafter, second device 2), a third device a signal carrier-plus-side signal generation of a wide channel (LFB HF) (hereinafter, the third device 3), a fourth wide-channel side-signal signal generating device (WB HF) (hereinafter, a fourth device 4), a directional coupler (BUT) of signals narrow channel (BUT UK) 5, for example wide channel signal coupler (NOC) 6, switchgear (RU) 7 with four inputs 71-74 and 2N outputs, linear antenna array (AR) 8 of 2N (hereinafter, N is an integer greater than or equal to two , n is the serial number of the device in a homogeneous group of devices: radiating elements of the AR, sensors, NO, matched loads, n≥1; the lower index number indicates the direction of the device relative to the center of the AR) radiating elements located symmetrically with respect to the center of the AR: N left 1 _lion , 2 _lion , ..., n _lion , ..., N _lion and N p equal to 1 _pr , 2 _pr , ..., n _pr , ..., N _{pr of} radiating elements, and the left and right radiating elements are counted from the center of the antenna array AR to its left and right edges, respectively, N left and right sensors 9 with reduction cables moreover, the sensors are located near the radiating elements of the AR, and the sensor has the same number as the number of the radiating element of the AR, N-1 left directional couplers (HO) 10 on the connected lines, N-1 right HO 10 on the connected lines 10, 2N -4 phasing cable segments 11, fixed phase shifter 12 by 90 °, bridge 13, divides 14 l capacity with first and second outputs, the first adder 15 with first and second inputs, the second adder 16 with first and second inputs, measuring the difference of depths of modulation (DDM)) 17 with three inputs, 2N-2 matched loads 18.

The first 1, second 2, third 3 and fourth 4 devices are generators that generate the above signals. These devices are made, for example, as they are made in serial radio beacons of the SP-90 meter wavelength range, manufactured by the Chelyabinsk Radio Plant "Polet" and operated at civilian aerodromes. HO 5, 6, 10, bridge 13, divider 14, adders 15, 16 are widely known, built on the basis of connected strip transmission lines. BUT is a four-arm device formed by two connected transmission lines. The line to the shoulder of which the source is connected is called the main line, the other line is called the connected line. Electromagnetic energy from the source is distributed between the output arm of the main line and one of the arms of the connected line. Energy does not enter the second arm of the connected line. This shoulder is called the untied shoulder. BUT is characterized by the voltage coupling coefficient K, equal to the square root of the ratio of the power in the arm of the connected line to the power at the input of the BUT. The output power of the main line is equal to the input power times 1-K ² . The switchgear is a multipole made on the basis of strip devices, calculated according to formulas from well-known reference books. Linear AR may contain from 12 to 24 or more radiating elements. As radiating elements of the AR, horizontally oriented half-wave vibrators or broadband symmetric vibrators (RF patent for invention No. 2357337) with a common reflector, log-periodic antennas without a reflector, wave channel antennas, etc. can be used. Sensors 9 are used in the form of short compared to the wavelength of the vibrators (L. Ya. Ilyinsky, A. A. Bolbot. Antenna devices of civil aviation airports. M: Transport. - 1983. - p. 53 (191).) or in the form of frames (US patent No. 4,107,688). Phasing segments are made of a standard phase-stable cable, such as, for example, PK-50-7-58C. As a 90 ° fixed phase shifter, a quarter-wave length of a standard cable can be used. The RGM meter is a receiver of high-frequency signals, in which, after detecting the received signals, tone modulation signals of 90 Hz and 150 Hz are isolated using bandpass filters. By comparing the amplitudes of the signals with frequencies of 90 Hz and 150 Hz, the difference in modulation depths is determined. RGM meters are widely used in the practice of operating radio beacons in aircraft landing systems.

imaginary unit. The phase factor e ^{± i90 °} means the phase shift of the signal by ± 90 ° relative to the phase of the LFN of the UK signal or the phase of the LPS of the HF signal. The laws of the distribution of the amplitudes of the mentioned signals over the emitting elements are determined by the known algorithms for the synthesis of antenna patterns (antenna) based on the requirements for the antenna for the said signals in the far zone. The signals mentioned at the input are radiated into the surrounding space, forming radiation patterns for the signals of the NFM UK, NF FM, NFB HF, HF HF. The AR forms for the signals of the NFM of the Criminal Code a narrow DN of the total form (bell-shaped form) with a maximum oriented in the direction of the runway axis. The AR forms a narrow differential-type DN (double bell type) for the BC warhead signals with a zero level oriented in the direction of the runway axis. The AR forms for the signals of the NSC HF a wide broad-area pattern in the form of a pedestal with a recess, the minimum of which is directed along the axis of the runway. AR forms for signals of BC HF a wide differential-type pattern with a zero level oriented in the direction of the runway axis.

Sensors located in the vicinity of the radiating elements of the AR, extract from the electromagnetic field the signals NBCH UK, BS UK, NBCH SHK, BC ShK (transmission coefficient IE sensor at minus 25 dB). Moreover, the normalized amplitude-phase distribution of these signals at the output of the sensors repeats the normalized amplitude-phase distribution of these signals on the radiating elements of the AR. The signals from the left sensors are fed to the LSU, the signals from the right sensors are fed to the LSU. The task of the LSU and the PSU is to sum the signals as they are summed in space in the far zone of the AR on the runway axis. To solve this problem, it is necessary, firstly, that the signals from all sensors would have the same attenuation, and, secondly, all the signals at the output of the LSU and at the output of the PSU would be in phase. Equal attenuation of signals in the LSI, as well as in the LSI, is ensured by the fact that BUT with different numbers n have different coupling coefficients. Denote α _n as the coefficient of transmission of the voltage signal from the n-th sensor to the output of the LSU (PSU). Obviously, α _n will be equal to the product of the coupling coefficient of the nth sensor and the transmission coefficients of n-1 BUT located on the portion of the signal propagation path from the said sensor to the output of the LSU:

The requirement of equality of transmission coefficients from each sensor to the output of the LSU (PSU) is reduced to the equality:

From equality

follows the recurrence relation for the values of the transmission coefficients BUT:

The lengths of the connecting cables from the sensors to the NO are the same, and therefore the attenuation is the same in all of the specified connecting cables. Therefore, the losses in the cables can not be taken into account, and the coupling coefficient of the N-th sensor with LSS (CSP), K _N , be taken equal to 1. Then:

Those. the coupling coefficient of the (N-1) th BUT should be minus 3 dB. The coupling coefficients of the previous ones according to the numbers of BUT are determined by the recurrence relation.

раз, где $${\epsilon }^{\prime }$$

- относительная диэлектрическая проницаемость диэлектрика коаксиальной линии передачи в случае сплошного заполнения и эквивалентная относительная диэлектрическая проницаемость в случае частичного заполнения кабеля диэлектриком. Кроме того, учтено, что при распространении по главной линии НО сигнал запаздывает на 90°. Таким образом, длины фазирующих отрезков 11 выбраны равными целому числу волн в кабеле минус четверть длины волны в кабеле. Число волн в кабеле выбрано, с учетом расстояния между излучателями в АР. Физическая длина кабеля должна быть равна или быть больше расстояния между излучающими элементами АР.The lengths of the phasing segments of the cable 11 are determined from the condition of the in-phase addition of signals from all left sensors at the output of the LSU and from all right sensors at the output of the PSU. Moreover, it was taken into account that the wave propagates in the cable more slowly than in free space in $$\sqrt{{\epsilon }^{\prime }}$$

times where $${\epsilon }^{\prime }$$

- the relative dielectric constant of the dielectric of the coaxial transmission line in the case of continuous filling and the equivalent relative dielectric constant in the case of partial filling of the cable with a dielectric. In addition, it was taken into account that when propagating along the main line of the BUT, the signal is delayed by 90 °. Thus, the lengths of the phasing segments 11 are chosen equal to an integer number of waves in the cable minus a quarter of the wavelength in the cable. The number of waves in the cable is selected, taking into account the distance between the emitters in the AR. The physical length of the cable should be equal to or greater than the distance between the radiating elements of the AR.

The signals U _LSU at the output of the LSU are equal to:

The signals at the output of the CCP are:

where ( a _{n yk} ) _lion , (b _{n yk} e ^{i90 °} ) _lion , ( a _{n yk} ) _pr , (b _{n yk} e ^{i90 °} ) _pr are the relative amplitudes and phases of the currents of the CC signals of the left and right sensors,

(A n shk) lion, (b n shk e i90 °) lion, (a n shk) straight, (b n shk e i90 °), etc. - the relative amplitudes and phases of signals SK currents left and right sensors.

The signals from the output of the LCS are fed through a fixed 90 ° phase shifter to the first input 131 of the bridge 13. As a bridge, a directional 3 dB BUT is applied, which arrives at its first input 131 without branching, branches to the first output 133 of the bridge and delays the signals of the LSB on the second 134 bridge exit at 90 °. The CCP signals are fed to the second 132 input of the bridge 13. The CCP signals without phase change branch to the second output of the bridge 134 and are delayed by 90 ° to the first 133 output of the bridge 13. As a result, the LCC and CCP signals are in-phase added to the first 133 output and out of phase to second 134 exit of the bridge. As a result, at the first 133 output of the bridge 13, the signals are summed in phase. The total signal U ₁₃₃ is equal to:

At the second 134 output of the bridge 13, the signals are summed out of phase. The total signal U ₁₃₄ is equal to:

With perfect tuning and perfect work of the CRM:

Therefore, with the perfect configuration of the CRM:

Then:

The signals from the first output of the bridge are fed to the first input of the RGM meter with the name "O" RGM. Since, in the ideal case, the signal from the first 133 output of the bridge does not contain a warhead signal, i.e. RGM signal is equal to zero, then the RGM meter will record zero values of the RGM. In the case when, for some reason, for example, in the event of failure of any radiating element, the presence of a layer of wet snow on the radiating element, etc., a warhead signal will appear at the output of the bridge as part of the total signal. In this case, the RGM meter will record a non-zero value of the RGM. Moreover, this value will be equal to the value of the RGM at points in the far zone of the AR on the axis of the runway.

The signals from the second 134 output of the bridge, containing in the ideal case only the signals of the warhead CC and warhead bar, are fed to the input of the divider, from the output of which they go to the first input of the first adder and to the first input of the second adder. The signal branched into the NO UK 5 NCH BC is fed to the second input of the first adder, the output of which is connected to the second input of the RGM meter with the name "S _yk ". The signal, branched into the NO HF 6 of the LFN HF, is fed to the second input of the second adder, the output of which is connected to the third input of the RGM meter with the name "S _hf ". At the output of the first adder, a signal can be generated whose RGM in a narrow channel is equal to the RGM value in the range from 10% to 20%. The wide channel signal from the second input of the RGM meter is filtered out by the mentioned device, this signal does not affect the measurements of the RGM UK. If errors occur in the amplitude-phase distribution of currents in the radiating elements of the AR, the corresponding signals of the CM RGM meter will show the deviation of the RGM meter readings from the previously set value. If the deviations of the readings of the RGM meter do not exceed 25% of the pre-set value of the RGM to indicate the steepness of the zone through a narrow channel, the RPC will continue to operate in normal mode, otherwise the RPC meter will give a warning signal about the violation of the RPC.

At the output of the second adder, a signal can be generated, the RGM of which over a wide channel is equal to the RGM in the range from 10% to 20%. The narrow channel signal from the third input of the RGM meter is filtered by the said device, this signal does not affect the measurements of the RGM HK. If errors occur in the amplitude-phase distribution of currents in the radiating elements of the AR corresponding to the HK signals, the RGM meter will show the deviation of the readings of the RGM meter from the previously set value of the RHM ShK. If the deviations of the readings of the RGM meter do not exceed 25% of the pre-set value of the RGM to indicate the steepness of the zone over a wide channel, the RPC will continue to operate in normal mode, otherwise the RPC meter will give a warning signal about the violation of the RPC. Thus, if during operation of the CRM deviations (defects) appear in the amplitude-phase distribution of the currents of the AR CRM, then this will lead to a change in the controlled values of the RCM: "0", S _y , S _n . The tolerance control system, based on a comparison of these changes with tolerances, makes a decision to either continue to operate the ASC or disable the ASC.

Examples of the implementation of the CRM in the first embodiment

As a specific implementation of the technical proposal, we consider a CRM with a 16-element antenna array for operation at a frequency of 110 MHz. Phasing cable segments are made of phase-stable cable RK-50-7-58C. The distances between the radiating elements of the AR are given in table 1.

Table 1 IE number 1 _lion 2 _lion 3 _lion 4 _lion 5 _lion 6 _lion 7 _lion 8 _lion 1 _pr 2 _pr 3 _pr 4 _pr 5 _pr 6 _pr 7 _pr 8 _ol Distance from the center, m 0.95 3.04 5.3 7.73 10.34 13.13 16.09 19.23 Distance between IE 2-1 3-2 4-3 5-4 6-5 7-6 8-7 2.09 2.26 2.43 2.61 2.79 2.96 3.32

The factor of shortening the wavelength in the cable RK-50-7-58C is 1.1.

Therefore, the wavelength in the cable λ _k at a frequency of 110 MHz is equal to:

Wherein:

меньше меньшего из расстояний между ИЭ. Поэтому он оказывается не пригодным в качестве фазирующего отрезка. Отрезок кабеля длиной $$2{\lambda }_{к}-\frac{{\lambda }_{к}}{4}$$

больше большего расстояния между ИЭ (3,32 м<4,338 м). Отрезки фазостабильного кабеля РК-50-7-58C длиной $$2{\lambda }_{к}-\frac{{\lambda }_{к}}{4}$$

приняты в качестве фазирующих отрезков в рассматриваемой антенне.Cable length $${\lambda }_{\mathrm{to}}-\frac{{\lambda }_{\mathrm{to}}}{\mathrm{four}}$$

less than the smaller of the distances between IE. Therefore, it is not suitable as a phasing segment. Cable length $$2{\lambda }_{\mathrm{to}}-\frac{{\lambda }_{\mathrm{to}}}{\mathrm{four}}$$

greater distance between IE (3.32 m <4.338 m). Pieces of phase-stable cable RK-50-7-58C long $$2{\lambda }_{\mathrm{to}}-\frac{{\lambda }_{\mathrm{to}}}{\mathrm{four}}$$

taken as phasing segments in the antenna under consideration.

To build the LSI and CSP, 7 pairs of directional couplers with the coupling coefficients indicated in Table 2 were used.

. При прохождении сигнала от наиболее удаленного НО, НО_{7 лев} или HO_{7 пр}, до выхода суммирующего устройства ЛСУ или ПСУ потери составят не более 0,21 дБ. При указанной величине затухания волны в кабеле нет необходимости корректировать коэффициенты связи, рассчитанные по рекуррентным соотношениям и указанные в табл.2.The loss of electromagnetic energy in the feeder is determined by the attenuation coefficient of the cable RK-50-7-58C at a frequency of 110 MHz, equal to $$0,008\frac{dB}{m}$$

. When the signal passes from the farthest BUT, BUT _{7 lion} or HO _{7 pr} , to the output of the summing device LSU or CSP, the loss will be no more than 0.21 dB. With the specified value of wave attenuation in the cable, there is no need to adjust the coupling coefficients calculated by the recurrence relations and indicated in Table 2.

На входы излучающих элементов с одинаковыми номерами n_лев=n_пр (n≠0) поступают:The dual-frequency CRM according to the second embodiment works as follows. The first device 1 generates signals NBC $$U_{nbh}^{\mathrm{at}\mathrm{to}}\left(t\right)$$

which are fed to the first input of 71 RU 7 along the main line of BUT UK 5; the second device generates signals of the warhead of the UK $$U_{bh}^{\mathrm{at}\mathrm{to}}\left(t\right)$$

that go to the second input 72 RU 7. The third device 3 generates signals NBC SHK $$U_{nbh}^{w\mathrm{to}}\left(t\right)$$

which are fed to the third input of 71 RU 7 along the main line NO ШК 6; the fourth device generates signals of the БК ШК $$U_{bh}^{w\mathrm{to}}\left(t\right)$$

, which are fed to the fourth input 74 RU 7. RU 7 distributes the received signals as follows. The inputs of the radiating elements with the same numbers n _lion = n _PR (n ≠ 0) are:

- common-mode signals of the NLF CC with equal amplitudes:

- antiphase signals of the warhead of the Criminal Code with equal amplitudes:

- common-mode signals of the NFB HF with equal amplitudes:

- antiphase signals of warheads of barrels with equal amplitudes

The central emitter (n = 0) receives the signals of the NFB UK and NFB HF with amplitudes ( a _{nbch yk} ) ₀ and ( a _{nbch hk} ) ₀ , respectively. The signals of the warhead CC and warhead CC are not received at the central radiating element,

(b _{bch yk} ) ₀ = (b _{bch yk} ) _n = 0.

The aforementioned signals received at the AR input are emitted into the surrounding space, forming a radiation pattern for the signals of the NFM UK, NF FM, NFB HF, HF HF. The AR forms for the signals of the NFM of the Criminal Code a narrow DN of the total form (bell-shaped form) with a maximum oriented in the direction of the runway axis. The AR forms a narrow differential-type DN (double bell type) for the BC warhead signals with a zero level oriented in the direction of the runway axis. The AR forms for the signals of the NSC HF a wide broad-area pattern in the form of a pedestal with a recess, the minimum of which is directed along the runway axis. AR forms for signals of BC HF a wide differential-type pattern with a zero level oriented in the direction of the runway axis.

Sensors located in the vicinity of the radiating elements of the AR, extract from the electromagnetic field a small fraction of the energy of the signals NBCH UK, BS UK, NBCH SHK, BC ShK (at -25 dB). Moreover, the normalized amplitude-phase distribution of these signals at the output of the sensors repeats the normalized amplitude-phase distribution of these signals on the radiating elements of the AR. The signals from the left sensors with numbers n ≠ 0 are sent directly to the LSU, the signals from the right sensors with numbers n ≠ 0 are sent directly to the LSU. The signals from the sensor with the number n = 0 (90) are divided by 3 dB by a power divider into two equal in amplitude and with the same phase of the signal, which are fed to the outputs 211 and 212. From the output 211, the signal is supplied to the NLS with the number n = 0 (100 _lion ). From the output 212, the signal is supplied to the BSS with the number n = 0 (100 _pr ).

LSU and PSU sum the signals from all sensors in the same way as the signals emitted by the AR are summed in space in the far zone on the runway axis. To solve this problem, it is necessary, firstly, that the signals from all sensors would have the same attenuation, and, secondly, all the signals at the output of the LSU and at the output of the PSU would be in phase. Equal attenuation of signals in the LSI, as well as in the LSI, is ensured by the fact that BUTs with different numbers n have transmission coefficients determined by the above recurrence formula for the voltage K _{n of the} signal from the nth sensor to the LSI output (LSI) (n = 0 , 1, ..., N).

The lengths of the phasing segments of the cable 11 are determined from the condition of the in-phase addition of signals from all left sensors at the output of the LSU and from all right sensors at the output of the PSU. The electrical length from the sensor 90 to the input of the NO 100 _lev (and also from the sensor 90 to the input of the NO 100 _pr ) should be equal to the electrical length of the connecting cables from the sensors to the NO with numbers n ≠ 0. Further, the description of the CRM operation in the second variant is similar to the description of the CRM operation in the first variant with an unprincipled difference, namely, that the summation in the formulas begins with n = 0, with b _{0 yk} = b _{0 wk} = 0.
