Description

The invention relates to communication technology, and more particularly to radio systems for transmitting and receiving radio signals and extracting information. Such systems include, in particular, radio navigation and radar systems, radio reconnaissance systems for radio equipment, radio surveillance of the Earth’s surface, etc. [Radio systems / Yu.M. Kazarinov et al. Ed. Yu.M. Kazarinova. - M .: IC "Academy", 2008, p. 7]. The inventive system contains radio signals receiving radio engineering objects, stationary or mobile, and a ground-based point radio signal transmitting system, including ordered numbered radio signal transmitting points, in an amount of at least five, the coordinates of the phase centers of the antennas of which are known at radio signal-receiving radio objects. The implementation of the system will make it possible, among other things, to determine the spatial coordinates of the indicated radio engineering objects, simplify the corresponding information extraction systems, and increase their technical and economic efficiency, taking into account all the components that affect the cost and technical indicators.

Known radio engineering systems for transmitting and receiving radio signals and extracting information are used, inter alia, to determine the coordinates of radio engineering objects and are based on the use of goniometric, rangefinder, difference and total-rangefinder and combined methods for determining the location of an object with amplitude, time, frequency, phase and pulse -phase methods for measuring the parameters of the radio signal [RF patents №№2018855, 2115137, 2258242, 2264598, 2309420, 2325666, 2363117, 2371737, 2378660; Fundamentals of testing aircraft / E.I. Krynetsky et al. Ed. E.I. Krynetsky. - M .: Mashinostr., 1979, p. 64-89; Radio engineering systems / Yu.M. Kazarinov et al. Ed. Yu.M. Kazarinova. - M .: IC "Academy", 2008, p.17-18, pp. 7.1-7.4, ch.10 .; Melnikov Yu.P., Popov SV. Radio intelligence. Methods for assessing the effectiveness of the determination of radiation sources. - M.: Radio Engineering, 2008, Ch. 5]. Known systems have certain disadvantages, for example, the need for mechanical movement of the antenna system, the impossibility of unambiguous determination of the coordinates of the object, the need for a priori information about the location of the object, the need for general synchronization of radio objects transmitting and receiving radio signals, and insufficient reliability. According to the criterion of minimum sufficiency, the closest is the system for transmitting and receiving radio signals and extracting information according to patent RU No. 2453996.

An advantage of the claimed system in comparison with the known ones is the possibility of increasing the technical and economic efficiency of radio engineering complexes for measuring spatial coordinates and other characteristics of an object functionally related to its coordinates, including ensuring the accuracy and reliability of their measurement in accordance with modern requirements. This is achieved by the fact that the claimed system, in particular, does not require general synchronization of the aggregate of transmitting and receiving radio signals of radio engineering objects. Also, the inventive system allows you to determine the spatial coordinates through indirect measurements using simple expressions that depend on the measured moments of the times of receiving radio signals at a radio signal receiving radio object. This simplifies the unambiguous determination of spatial coordinates.

Figure 1 shows the inventive system. The radio system 1 contains a ground-based point-to-point radio signal transmitting system (PS) 2 and a radio signal receiving (radio) radio engineering object (RO) 3. In this case, the MS 2 includes orderly numbered radio transmitting points 4 (No. 1, 2, ..., n, ..., N) in an amount of N less than five. Each of them contains antenna devices 5, the phase centers of the transmitting antennas of which are in predetermined, not located in the same plane, and known, including at the mentioned objects, points with coordinates X _n , Y _n , Z _n , where the index n varies from 1 to N, respectively, in a given three-dimensional Cartesian coordinate system (X, Y, Z). Radio antenna devices 5 are connected to antenna devices 5.

Devices 6 are configured to synchronize an ordered transmission of p / s series, mainly one p / s from each transmitting p / s point 4 in the series, and with specified not necessarily the same intervals between the series. If necessary, the device 6 is made with the possibility of transmitting r / s with predetermined individual characteristics, including complex and composite r / s with predetermined individual signs of their elements [L. Varakin Theory of signal systems. M .: Sov. radio, 1978, p.18] and the possibility of their separation when receiving. Also, if necessary, the device 6 is made with the possibility of transmitting r / s with predetermined, not necessarily the same, and known on the mentioned receiving r / s PO 3 time delays between r / s.

Each receiving r / s PO 3 contains an antenna device 7 and a receiving r / s device 8 connected to it. The latter is configured to receive the r / s of the ground PS 2 and identify them with the corresponding transmitting r / s points 4. The PO 3 contains a recorder of 9 moments the time of receiving r / s from transmitting r / s points 4 in the time reference system set for PO 3. The registrar 9 is connected to the receiving r / s device 8. The PO 3 contains an information system 10 operably connected to the registrar 9 and configured to store the given coordinates X _n , Y _n , Z _n , given delay times, if necessary, and parameters a _i defined in accordance with expressions (1). Also, the information system 10 is configured to center, if necessary, the indicated moments of the reception times p / s, including, if necessary, with the indicated delay times excluded, and to determine the thus recorded moments of the times t _n and measure the mentioned parameters d _n , measure the mentioned parameters c _j , AC _k , b _l , BX _m , BY _m , BZ _m in accordance with the measurement equations (2), (3), (4) and (5). In addition, the information system 10 is configured to measure the spatial coordinates of the phase center of the antenna of the antenna device 7 receiving r / s PO 3 mainly in accordance with the measurement equations (6).

If necessary, the information system (10) is configured to save the measured x, y, z coordinates in series, and to measure other path characteristics of PO 3 through them, including using statistical methods of path measurements. At the same time, PO 3, if necessary, contains a display unit 11 and a unit for transmitting information to consumers 12, functionally connected with the information system 10. PS 2, if necessary, contains a unit for receiving and displaying information 13, configured to receive information transmitted by the specified unit for transmitting information to consumers 12 of PO 3.

In addition, if necessary, in PS 2, a control receiver of the radio engineering object (CRO) 14 is introduced, configured to receive radio communications transmitted by points 4 with the coordinates of the phase center specified in the indicated three-dimensional Cartesian coordinate system (X, Y, Z) its antennas x _k , y _k , z _k , the constituent elements of which are made essentially identical to the constituent elements of PO 3. Moreover, the information system 10 of the KPO 14 is additionally configured to correct said measured coordinates x, y, z by known coordinates x _k , y _k , z _k and the measured coordinates x _ki , y _ki , z _{ki of the} phase center of the receiving antenna KRO 14. Also, the PS 2 contains a subsystem 15 for controlling its operation.

The proposed system 1 operates as follows.

MS 2 transmits r / s synchronously. In this case, the r / s are transmitted in order by series, mainly one r / s from each transmitting r / s point 4 containing the antenna device 5 and the transmitting r / s device 6, in a series. The intervals between series are not necessarily the same. If necessary, transmitting r / s points 4 transmit r / s with predetermined individual characteristics, including complex and composite r / s with predetermined individual characteristics of their elements and the possibility of their separation during reception. Also, if necessary, p / s are transmitted with predetermined, not necessarily the same, and known by PO 3 time delays between p / s.

The radio signals are received at a specific PO 3 and identified by their respective transmitting p / s points 4. At this object, the registrar 9 records the times of receiving p / s in a given time reference system. If necessary, in the information system 10, the corresponding indicated delay times are excluded from them. In it, the indicated moments of the reception times of the radio receivers with excluded delay times are, if necessary, centered by eliminating from each moment of time the average value of all the moments of the series. Based on the thus recorded time instants t _n, said parameters d _n are measured. In the information system 10 PO 3 through the specified coordinates X _n , Y _n , Z _n determine (for a specific PS 2 once) the parameters a _i in accordance with expressions (1). Through the mentioned X _n , Y _n , Z _n and the measured parameters d _n, the parameters c _j are measured in accordance with the measurement equations (2). Using parameters a _j and c _j, the parameters AC _k are measured in accordance with the measurement equations (3). In addition, through the above-mentioned X _n , Y _n , Z _n and through the measured parameters d _n, the parameters b _l are measured in accordance with the measurement equations (4). Through the parameters a _i and c _j, the parameters BX _m , BY _m , BZ _m are measured in accordance with the measurement equations (5). And finally, the spatial coordinates x, y, z of the phase center of the receiving antenna PO 3 are measured mainly in accordance with the measurement equations (6). If necessary, the series and all the indicated actions in them are repeated and other trajectory characteristics of this object are measured using the x, y, z PO 3 coordinates measured in the series, including using statistical methods of trajectory measurements. If necessary, this information is displayed and transmitted to consumers in blocks 11 and 12, respectively. If necessary, the information transmitted to consumers is received and displayed in block 13 on PS 2.

In addition, if necessary, r / s PS 2 is also received at KRO 14 with the coordinates of the phase center of its receiving antenna x _k , y _k , z _k specified in the indicated three-dimensional Cartesian coordinate system (X, Y, Z). At the same time, at KPO 14 p / s, it is taken predominantly identical to receiving p / s at PO 3. The coordinates x _ki , y _ki , z _{ki of the} phase center of the receiving antenna KPO 14 are measured identically to the specified coordinate measurement of PO 3. Then the measured coordinates x, y, are corrected z PO 3 according to the known coordinates x _k , y _k , z _k and the measured coordinates x _ki , y _ki , z _{ki of the} phase center of the receiving antenna KRO 14.

We list the main advantages of the system:

- provides an unambiguous determination of the spatial coordinates of the object with great accuracy, corresponding to modern requirements,
