Description

The invention relates to radio engineering and can be used to increase the efficiency of a jamming station (SP) by increasing its channel in the number of suppressed pulse-Doppler (ID) radar detection and tracking of trajectories.

(Electronic Radio Countermeasure System. US Patent No. 4307400. 1981, G01S 13/40.)

A disadvantage of the known electronic radio countermeasures system is its low channel, because under conditions when several antenna targets operating at different frequencies are located in its antenna pattern (BPS), only one of them will be suppressed.

(Radio interference station with automatic tuning to the frequency of the suppressed medium. US Patent No. 3431496. 1966. H04K 3/00.)

A disadvantage of the known jamming station (SP) is that it is single-channel in terms of the number of targets served under conditions where there may be several of them in the DND.

The closest in technical essence to the claimed jamming station is a device for interfering with radar stations containing a receiving antenna, an input key, a high frequency amplifier (UHF), a splitter, an adder, frequency channels with bandpass filters and a key circuit consisting of a detector, a video amplifier, a shaper of a control signal, a key, a radar survey cycle duration measuring unit, consisting of a threshold element, a key, a separate trigger, a differentiating circuit, a diode limiter, a waiting multivibrator, a trigger with a controlled counting start, a time interval meter, as well as a channel key, a strobe pulse generator, a switch, a control and synchronization unit, a decoder, an UHF output and a transmitting antenna, the output of the input key connected to the output of the receiving antenna by the first input , the second input with the first output of the strobe generator, connected to the input high-frequency amplifier, the output of which is connected to the inputs of the splitter and switch, the output of which is connected to the first input in the output UHF, the output of which is connected to the transmitting antenna, the second input of the output UHF is connected to the second output of the pulse strobe generator, N outputs of the splitter are connected to the corresponding inputs of N bandpass filters of the frequency channels, and in each frequency channel the output of the bandpass filter is connected to the first key input of the key the circuit, the output of which is connected to the first input of the channel key of the key circuit and the detector, the output of which is connected to the input of the video amplifier, the first output of which is connected to the input of the signal driver alarm, and the second with a series-connected threshold element, key, trigger with separate start, differentiating circuit, diode limiter, waiting for a multivibrator, the output of which is connected to the second inputs of the key and trigger with separate start, trigger with controlled counting start, time interval meter measuring unit the duration of the radar review cycle, the output of the driver of the control signal of the key circuit is connected to the second input of the key of the key circuit, the output of the adder, N inputs of which are connected to the corresponding outputs of the key circuits, connected to the first input of the output UHF, a control and synchronization unit that selects the frequency channel and generates interference parameters, N inputs of which are connected to the measurement units of the radar scan cycle time of the corresponding channel and whose output is connected to the decoder input, N outputs of which connected to the inputs of channel keys of the respective channels. (A device for interfering with radar stations. RF patent No. 2054807. 1994. Н04К 3/00, G01S 7/32 (Prototype).)

A disadvantage of the known device is that it interferes with several airborne radars for detecting and tracking trajectories operating at different frequencies (in different frequency channels) and located in the BOTTOM of a device for creating interference only when suppressing radars for detecting and tracking trajectories using the tie-in algorithm (detection) of the trajectories “k out of 1” (k and 1 is the number of radar scan cycles) k equal to 1 (in practice, the detection logic “2 out of 2”, “2 out of 3”, “3 out of 3”, “ 3 of 4 "(V.S. Verba, Aviation Comp eksy radar surveillance and guidance -. M .: Radio Engineering, 2008, p.140)), i.e. it is sufficient to provide acceptable quality decrease below detection in one of its 1 reviews and complication (detection) paths will be foiled. Thus, the suppression of several radar detection and tracking of trajectories.

For example, if the radiations of several radars are simultaneously received in different frequency channels with the “2 of 3” or “3 of 4” tracing (detection) logic used in them, the jamming device needs to reduce below the permissible tracing [tracing] detection (detection) detection quality in two of 1 of its reviews, that is, it will provide suppression of only one (detection logic "2 of 3"), or two (detection logic "3 of 4") radar detection and tracking of trajectories.

The objective of the present invention is to increase the efficiency of the joint venture by increasing its channel in the number of suppressed ID radar detection and tracking of trajectories by creating intermittent interference using the features of their functioning.

For radar data, along with the need for linking (detecting) the trajectories of the “k out of 1” algorithm, it is necessary to uniquely determine the range to the targets to receive all z packets of the emitted signal. (The reference book on radar. T.3. Radar devices and systems. / Under the editorship of M. Skolnik. - M .: Sov. Radio, 1979. P.378.)

The determination of the range using several (usually three) fixed pulse repetition frequencies requires sequential ambiguous measurement of the range at each repetition frequency, followed by comparison of the measurement results and elimination of the ambiguity.

The need for a radar detector ID for tracking and tracking trajectories to uniquely determine the reception range of all z packets of the emitted signal, using the criteria “k out of 1” in the tracing (detection) algorithm to suppress it by lowering at least one of the emitted packets below the acceptable detection quality signal (to achieve this effect, interference can be intermittent response noise, synchronized with the radiation of one of the signal packets), and a decrease below the permissible achestva detection by the radar in its reviews m. The duration and period of intermittent interference is selected from the condition

,

,

where z is the number of bursts of signal pulses used in the radar ID with its own pulse repetition rate (SIP);

M _i is the number of pulses in the i-th signal packet;

T _ci is the pulse repetition period in the i-th signal packet;

τ _CR , T _CR - the duration and period of intermittent interference.

Pauses of intermittent interference make it possible (without reducing the power density of the interference) to create intermittent interference at other frequencies, which allows to increase the channelity of the SP.

Figure 1, a shows the possibility of increasing the number of suppressed radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the BOTTOM of the SP with the logic used to tie (detect) the trajectories “3 out of 4” and z equal to three for the use of interference only to break the set (detection) of trajectories by lowering the acceptable detection quality in two of its four surveys (* - the existing device for creating interference) and when using the interference to break the set (detection) of trajectories for by reducing below the acceptable detection quality in two of its four surveys, and disrupting the unambiguous determination of the range to targets by lowering below the acceptable detection quality of one of the packets of the emitted signal (** - proposed SP). Figure 1, b shows the possibility of increasing the number of suppressed radar ID detection and tracking of trajectories operating in different frequency channels and located in the bottom of the joint venture with the logic used for them to tie (detect) trajectories "3 out of 4" and z equal to three when using interference only to break the set (detection) of trajectories by lowering the acceptable detection quality in three of its four surveys (* - the existing device for creating interference) and when using interference as to break the set (detection) of trajectories for Thu drop below acceptable quality detected in three of its four surveys, and collapse unambiguous determination of range to the target due to drop below acceptable quality detecting audio packs of the emitted signal (** - the proposed SP). Figure 1, c shows the possibility of increasing the number of suppressed radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the DN of the joint venture with the logic for linking (detecting) the trajectories “3 of 3”, “2 of 3” and “ 2 out of 2 ”and z, equal to three, when using in the joint venture to break the ties (detection) of the reduction paths below the acceptable detection quality in two out of four (***) and three out of four (****) reviews and to break unambiguous determination of the range to the goal of reducing below the acceptable quality zheniya audio packs of the emitted signal.

Figure 1 indicates: N is the number of the review cycle ID of the radar detection and tracking of trajectories; f _i is the frequency of the radiated interference of the i-th ID of the radar for detecting and tracking trajectories; z _j - bursts of signal pulses used in the radar ID with its pulse repetition rate.

The analysis shows:

1. A joint decrease below the acceptable detection quality in two of four (three out of four) of its reviews, and a decrease below the acceptable detection quality of one of the bundles of the emitted signal compared to only a decrease below the acceptable detection quality in two out of four (three of four) leads to an increase in the number of suppressed radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the SPD from two to six (from one to three) (Fig. 1, a and 1, b).

2. The use in the radar ID of detection and tracking of trajectories of the logic of tie-in (detection) of the trajectories “3 of 3”, “2 of 3” and “2 of 2” and z equal to three, while lowering the acceptable detection quality in three out of four reviews and lowering below the acceptable detection quality of one of the packets of the emitted signal allows suppressing, for all logic, the link (detection) of the trajectories up to three radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the bottom of the SP (Fig. 1, c - *** *).

3. The use in the radar ID of detection and tracking of trajectories of the logic of the tie (detection) of trajectories “3 of 3” and z equal to three, while lowering the acceptable detection quality in two of its four surveys and lowering the acceptable detection quality of one of the packets of the emitted signal allows you to suppress up to six radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the bottom of the SP. Using the logic of tie-in (detection) of the “2 out of 3” trajectories, z equal to three, while lowering below the acceptable detection quality in two of its four surveys and lowering below the acceptable detection quality of one of the packets of the emitted signal, it allows to suppress the first three ID radar detection and tracking of trajectories, then for six reviews the second three ID radar detection and tracking of trajectories, the use of logic tie-in (detection) of the trajectories "2 of 2", z equal to three, with a decrease below the acceptable detection quality in two of its four surveys and lowering the acceptable detection quality of one of the packets of the emitted signal, it allows to suppress the first three IDs of radar for detecting and tracking trajectories, then for two reviews the second three IDs of radar for detecting and tracking trajectories, that is, they are characterized by a lack of stability of suppression (Fig. 1, c - ***).

4. With a priori uncertainty in the joint venture about the algorithm for linking (detecting) the trajectories of the detection and tracking of trajectories used in the radar ID, the most acceptable jamming algorithm with it, which gives a guaranteed result in the number of suppressed radar IDs of tracking and tracking of trajectories, is to reduce the detection quality to a lower three of its four reviews and a decrease below the acceptable quality of detection of one of the packets of the emitted signal. It gives a stable result for all trajectory logics used for tracking and tracking trajectory logics (3 out of 4, 3 out of 3, 2 out of 3, and 2 out of 2), equal to three suppressed IDs Radar detection and tracking of trajectories operating in various frequency channels and located in the bottom of the SP. If it is possible at the joint venture to determine the logics of tracking (detecting) trajectories used in the radar ID and to obtain this information from external sources, it is possible to select the optimal version of the suppression algorithm in the reviews. When using the logic of linking (detecting) the trajectories “3 of 4” (“3 of 3”) and z equal to three, a decrease is lower than the acceptable detection quality in two out of four (in one of three) surveys and a decrease is lower than the acceptable quality of detecting one of the packets of the emitted signal will allow suppressing six (nine) radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the bottom of the joint venture, using the “2 out of 3” trajectory (detection) logic (“2 out of 2” ) and z equal to three, a decrease below the permissible detection quality in two of its three (in one of two) surveys and a decrease below the acceptable detection quality of one of the packets of the emitted signal will allow suppressing three (six) radar IDs for detecting and tracking trajectories operating in different frequency channels and located in the bottom of the SP, i.e. leads to an increase in the number of suppressed ID radar detection and tracking of trajectories (figure 1, g).

The jamming station operates as follows.

The signals received by the receiving antenna 1, through the input key 2 open in reconnaissance mode, amplified by the input UHF 3, in accordance with its carrier frequency, pass through the bandpass filter 6 together with the noise signal into one of the frequency channels where the detector 7 is detected, amplified by a video amplifier and arrive at the shaper of the control signal 9 and the block 16 measuring the duration of the radar scan cycle. In response to the incoming signal, the amplitude of which exceeds a certain threshold level of the driver U of the control signal U in this frequency channel, the key 10 closes. In the block 16 for measuring the duration of the radar scan cycle, signals exceeding the threshold of the threshold element 19 are transmitted through the key 20 which is open in the initial state arrive at the first input of the trigger 21 with a separate start, overturn it. In addition, the signals from the output of the threshold element 19 are supplied to the device 27 for generating a sign of the presence of a radar ID in the bottom of the SP and determining the number of NPIs used in it.

At the output of the differentiating circuit 22, a pointed pulse is generated, which is fed through the diode limiter 23 to the input of the standby multivibrator 24 and starts it. The pulse duration of the waiting multivibrator 24 is selected from the condition that the duration of the exposure of the onboard radar of the interference station in the review is exceeded. The pulse from the output of the standby multivibrator 24 is supplied to the trigger 25 with a controlled counting start, to the second input of the key 20 and the second input of the trigger 21 with a separate start. Under the influence of a pulse from the output of the waiting multivibrator 24, the trigger 21 is tipped over with a separate start to the initial state, the trigger 25 is tipped over with a controlled counting start, and the key 20 stops transmitting radar pulses to the input of the radar survey cycle measuring unit 16 for the duration of the ID time The radar detection and tracking of trajectories continues to be aimed at the joint venture.

In the next cycle of the ID survey of the radar detection and tracking of trajectories, all the described work of the SP is repeated. In this case, the trigger 25 with a controlled counting start is repeatedly overturned. At its output, according to the results of two cycles of a review of the ID of the radar for detecting and tracking trajectories, an impulse equal to the duration of the review cycle of this radar is taken. This pulse is supplied to the input of the meter 26 time intervals of this channel and to the input of the device 28 for determining the number of emitting radars in the bottom of the SP corresponding to this frequency channel.

Information about the duration of the review cycle of the ID of the radar for detecting and tracking trajectories in a given frequency channel t (i) in the form of a digital code is received from the output of a time interval meter 26 to the input of a control and synchronization unit 17 corresponding to this frequency channel. Similar information is supplied to the corresponding inputs of the control and synchronization unit 17 from other frequency channels.

In the device 27 for generating a sign of the presence of a radar ID in the bottom of the joint venture and determining the number of SIP used in it, the signals are fed to the first inputs of the M circuits I 27-2-2 ... 27- (M + 1) -2 and M delay lines 27-2 -1 ... 27- (M + 1) -1. The delay time - τ _s for all delay lines is different and lies in the range from minimum to maximum SIP of pulse-Doppler radars for detecting and tracking trajectories with discreteness equal to the pulse duration of this radar.

The pulses will appear at the output of the And 27-2-2 ... 27- (M + 1) -2 circuit, for which the radar pulse repetition periods and the delay time τ _s will coincide.

Thus, at two (three) outputs of the I 27-2-2 ... 27- (M + 1) -2 circuits (determined by pulse-Doppler radar for detecting and tracking trajectories by the number of SIPs), sequences of pulses differing in each other are formed sequentially in time from another pulse repetition period.

The pulse sequences of one SIP are supplied to the first inputs of the corresponding triggers 27-2-3 ... 27- (M + 1) -3 of their channels 27-2 ... 27- (M + 1) measuring the pulse repetition periods, as well as to the inputs (M- 1) OR circuits 27-2-4 ... 27- (M + 1) -4 of the remaining channels for measuring the pulse repetition periods of the device 27 for developing a sign of the presence of a radar ID in the bottom of the joint venture and determining the number of STIs used in it of this channel and then on to the second the inputs of the remaining (M-1) triggers 27-2-3 ... 27- (M + 1) -3 channels 27-2 ... 27- (M + 1) measure the pulse repetition periods.

The pulses received at the first input of the triggers are pulses of the “beginning” of the encoded time interval. The pulses received at the second input of the triggers are the pulses of the "end" of the encoded time interval. The pulses of one SIP, being the pulses of the "beginning" of the encoded time interval for one trigger, are the pulses of the "end" of the coded time interval for the remaining triggers of this frequency channel, due to the fact that the sequence of pulses at different SIPs follow sequentially in time and pass through different measurement channels pulse repetition periods of a given frequency channel.

The output signal of the triggers 27-2-3 ... 27- (M + 1) -3 channels 27-2 ... 27- (M + 1) measurement of the pulse repetition periods has the shape of a rectangular pulse with an amplitude equal to the logical level of "1", and the duration equal to the length of the encoded interval. The specified pulse from the outputs of the triggers 27-2-3 ... 27- (M + 1) -3 is supplied to the first inputs of the circuits And 27-2-5 ... 27- (M + 1) -5 of its channels 27-2 ... 27- ( M + 1) measuring the pulse repetition periods of a given frequency channel, as well as on the corresponding channel 27-2 ... 27- (M + 1) measuring the pulse repetition periods, the input of the device number 27-1 for determining the number of SIPs used in the radar ID of a given frequency channel. Pulses of a clock generator with a repetition period T _g come from the first output of the control and synchronization unit 17 to the second inputs of circuits I 27-2-5 ... 27- (M + 1) -5 of the remaining channels 27-2 ... 27- (M + 1) measuring pulse repetition periods. Only those pulses of the clock sequence that coincide in time with the pulses of the triggers 27-2-3 ... 27- (M + 1) -3 are transmitted to the output of coincidence circuits 27-2-5 ... 27- (M + 1) -5. Further signal conversion consists in counting the number of pulses from the outputs of matching circuits 27-2-5 ... 27- (M + 1) -5 and displaying the counting result in a parallel binary code. The count of the number of pulses is carried out by counters 27-2-6 ... 27- (M + 1) -6. The number of bits of the counter is selected based on the expected maximum value of the duration of work on one NPI.

Information about the duration of the pulse-Doppler radar for detecting and tracking trajectories at each of the SIPs in a given frequency channel t (i, j) in the form of a digital parallel code is supplied to the corresponding one of the M inputs corresponding to this frequency channel of the control and synchronization unit 17. Thus, encoded information about the duration of operation on two (three) STIs of a pulse-Doppler radar for detecting and tracking trajectories can be received from one frequency channel into the control and synchronization unit 17. Similar information is supplied to the corresponding inputs of the control and synchronization unit 17 from other frequency channels.

In the device 27-1 for determining the number of NPIs used in the radar ID of detecting and tracking trajectories, pulses from the outputs of triggers 27-2-3 ... 27- (M + 1) -3 channels 27-2 ... 27- (M + 1) measurements pulse repetition periods of a given frequency channel are supplied to the corresponding inputs of inverters 27-1-5-1 ... 27-1-5-M. At the outputs of two (three) differentiating circuits 27-1-4-1 ... 27-1-4-M at the end of the pulses of triggers 27-2-3 ... 27- (M + 1) -3 channels 27-2 ... 27- ( M + 1) measuring the pulse repetition periods of a given frequency channel with a changed polarity of inverters 27-1-5-1 ... 27-1-5-M polarity sharp-pointed pulses are formed, which through the corresponding diode limiters 27-1-3-1 ... 27-1 -3-M are fed to the input circuit OR 27-1-2. From the output of the OR 27-1-2 circuit, the pulses are sent to the counter 27-1-1 of the device 27-1 for determining the number of UHFs used in the radar ID of detection and tracking of trajectories of a given frequency channel, and are a sign of the presence of a radar ID of detection and tracking of paths in the frequency channel for device 29 for determining the number of emitting radar IDs. Information about the number of NIPs used in the radar ID of detection and tracking of trajectories in a given frequency channel, in the form of a digital code, comes from the output of the counter 27-1-1 to the input of the control and synchronization unit 17 corresponding to this frequency channel.

Thus, due to the fact that the pulses of one SIP, being the pulses of the "beginning" of the encoded time interval for one trigger 27-2-3 ... 27- (M + 1) -3, are the pulses of the "end" of the encoded time interval for the other triggers 27 -2-3 ... 27- (M + 1) -3 of a given frequency channel and the fact that the sequence of pulses at different NPIs follow sequentially in time and pass through different channels for measuring the pulse repetition periods of a given frequency channel, the possibility of “end” pulses is realized coded time slots the ability to determine the number of NIPs used in the radar ID of detection and tracking of trajectories of a given frequency channel, and to give a sign of the presence of a radar ID of detection and tracking of paths in a frequency channel.

In the device 28 for determining the number of emitting radars in the bottom of the SP, the pulses from the outputs of the triggers 25 with a controlled counting start of the frequency channels are supplied to the corresponding inputs of the differentiating circuits 28-3-1 ... 28-3-N. At the outputs of the differentiating circuits 28-3-1 ... 28-3-N, spiky pulses are generated, which are fed to the input of the OR circuit 28-1 through the corresponding diode limiters 28-4-1 ... 28-4-N. From the output of the OR 28-1 circuit, the pulses are fed to the counter 28-2 of the device 28 for determining the number of emitting radars in the bottom of the SP. Information about the number of emitting radars in the bottom of the SP (Q) in the form of a digital code comes from the output of the counter 28-2 to the second input of the control and synchronization unit 17.

In the device 29 for determining the number of radiating ID radar pulses from the outputs of the circuits OR 27-1-2 of the frequency channels are supplied to the first inputs of the triggers 29-4-1 ... 29-4-N corresponding to the frequency channel and overturn it. At the outputs of the differentiating circuits 29-5-1 ... 29-5-N, pointed pulses are formed, which are fed through the diode limiters 29-6-1 ... 29-6-N to the corresponding input of the second OR circuit 29-2. From the output of the second OR circuit 29-2, the pulses arrive at the counter 29-3 of the device 29 for determining the number of emitting radar IDs. Information about the number of emitting radar IDs in the bottom of the SP (R) in the form of a digital code comes from the output of the counter 29-3 to the first input of the control and synchronization unit 17. The pulses from the output of the decoder 11 are fed to the first circuit OR 29-1. From the output of the first circuit OR 29-1 pulses are fed to the second inputs of the triggers 29-4-1 ... 29-4-N and overturn them to their original state.

In the control and synchronization unit 17, based on the information received from the frequency channels (the duration of the review cycles of the radar ID of detection and tracking of trajectories in frequency channels, the number of used SIPs and information about the duration of each radar ID of tracking and tracking of trajectories in this frequency channel) , devices for determining the number of emitting radars and radar IDs, a solution is developed (one of the variants of the implemented algorithm in the control and synchronization block 17 is shown in Fig. 3) about the frequency nals (N), which will be used to interfere, and interference parameters (duration - τ _n , period - T _n ) in each of the suppressed frequency channels.

In accordance with this decision, the control and synchronization unit 17 in the jamming mode will provide information in the form of digital codes about the numbers of the frequency channels to the decoder 11. The decoder 11, recognizing the code combination, provides a control signal from the corresponding output to the channel key 18 corresponding to the code combination. The duration of each control signal determines the duration of the interfering signal for a given channel, determined by the control and synchronization unit 17.

Thus, the channel key 18 of the corresponding channel will open for a time equal to the duration and with the repetition period of the interference in this frequency channel.

The interference signal is generated by modulating the received radar signal with thermal noise, passing through the public keys 10, through which the signals are received, channel keys 18, which received the control signal from the decoder 11, the subsequent summation of the signals in the adder 12 and amplification in the output UHF 13.

Intermittent noise from the output of the output of the UHF 13 is fed to the transmitting antenna 15 and is radiated in the direction of the suppressed radar ID detection and tracking of trajectories. When information on the operation of the radar ID of the detection and tracking of trajectories from several frequency channels is received on the control and synchronization unit 17, it, in accordance with its algorithm, determines the number of suppressed radars, the order of their suppression, and the parameters of intermittent interference in the frequency channels.

Thus, the invention consists in eliminating the reception of a pulse-Doppler radar for detecting and tracking trajectories as one of the bursts of pulses of its complex signal, consisting of z bursts, and thereby disrupting the unambiguous measurement of the distance to the target in this radar, and in eliminating the detection of this radar in m of her reviews. This allows the proposed interference station, in comparison with the prototype device, to suppress a larger number of pulse-Doppler radar detection and tracking of trajectories operating at different frequencies and located in the bottom of the SP without reducing the power density of the interference. So, with a priori uncertainty in the joint venture about the algorithm for linking (detecting) the trajectories of the detection and tracking of trajectories used in the radar ID, the most acceptable jamming algorithm for it, which gives a guaranteed result in the number of suppressed radar IDs of tracking and tracking of trajectories, is to lower the acceptable detection quality in three of four of its reviews and a decrease below the acceptable quality of detection of one of the packets of the emitted signal and giving a stable result for all Mykh in SEQ ID radar detection and tracking paths logics drawstrings (detection) trajectories ( "3 4", "3 3", "2 out of 3" and "2 of 2") equal to three. If it is possible at the joint venture to determine the logics of tracking (tracking) trajectories used in the radar ID and to obtain this information from external sources, it is possible to select the best option for the suppression algorithm in surveys and thereby increase the number of suppressed radar IDs for detecting and tracking trajectories . So, when using the logic of tie-in (detection) of the trajectories “3 of 4” (“3 of 3”) and z equal to three, a decrease is lower than the acceptable quality of detection in two out of four (in one of three) surveys and a decrease is lower than the acceptable the detection quality of one of the packets of the emitted signal will increase the number of suppressed radar IDs for detecting and tracking trajectories up to six (nine). When using the logic of linking (detecting) the trajectories “2 of 3” (“2 of 2”) and z equal to three, a decrease is lower than the acceptable quality of detection in two of the three (in one of two) surveys and a decrease is lower than the acceptable quality detection of one of the packets of the emitted signal will increase the number of suppressed radar ID detection and tracking of trajectories to three (six).
