Description

The utility model relates to radar and can be used to detect, measure coordinates, identify and track a wide class of aerodynamic and ballistic objects.

Known radar meter wavelengths of a similar purpose [1, 2]. The disadvantages of these radars are low tactical, technical and operational characteristics (accuracy, detection zone, reliability, mobility, etc.).

The closest in technical essence and purpose to the proposed one is a mobile radar circular view of the meter wavelength range [3], adopted as a prototype.

The prototype radar is located on one vehicle (excluding the power supply system and the operator’s remote workstation) and contains an antenna mast device (AMU) made in the form of a single metal frame rotating with the help of a rotary support device (OPU), on which the main an antenna, which is an active phased antenna array (AFAR) of 6 rows and 14 columns with transceiver modules (MRP), a compensation antenna, a ground-based radio interrogator antenna (NRZ), a deployment unit Nia and coagulation beamforming unit (DOU) and telecode link antenna and a sounding pulse generator, the receiver, the primary and secondary processing device, a display device, control and monitoring apparatus NRZ and orienting apparatus and topographic location (TX).

The radar prototype provides detection, measurement of coordinates (range and azimuth), as well as elevation (ranging from 5 to 45 °), recognition and tracking of a wide class of aerodynamic and ballistic objects.

The main disadvantage of the radar prototype is the need for significant time costs for rolling up and deploying the main and compensation antennas, for leveling the vehicle platform, for cable connections between the radar and the power supply system, i.e. lack of mobility (up to 30 minutes). In addition, when using stationary power supply, the radar loses its autonomy, and when using a mobile power supply system (on a trailer), the radar maneuverability worsens when it is relocated, especially in mountainous areas.

The disadvantages of the prototype should be attributed to its low reliability (mean time between failures) due to the large number of APMs in AFAR AO 2 (84 pieces) and the presence of a high-frequency current collector, which negatively affects the reliability of the radar, as well as low productivity.

The main technical result of the proposed utility model is to improve the operational characteristics of the radar (mobility, maneuverability, autonomy and reliability)

An additional technical result is an increase in productivity, a decrease in the cost and overall dimensions of the radar.

These technical results are achieved by the fact that in the known radar prototype, placed on one vehicle (excluding the power supply system), and containing the antenna-hardware complex (AAK) 1 as part of the antenna of the main (AO) 2, beam-forming device (DOU) 3 , orientation and topographic referencing (UORT) 4, compensation antenna (AK) 5, transceiver device (PPU) 6, primary processing device (UPR) 7, deployment-coagulation device (URS) 9, antennas and equipment NRZ 10, secondary processing devices (UVO ) 11 and antennas for the telecode communication channel (ATCS) 12, as well as a control, display and control device (УУОК) 8, an autonomous power supply system (SAES) 13 has been introduced, including a power take-off generator (PTO), a diesel power station (DES) and an on-off unit and the distribution of primary power supply, and also reduced the number of lines in the AFAR AO2 to 4 and MRP to 56. In this case, the AAK 1 during operation of the radar rotates with its constituent devices in the azimuthal plane using the OPU, which ensures the operation of the radar without using high-frequency kosemnika and URS 9 further provides an automatic leveling the vehicle platform. In addition, the proposed radar is made on a modern elemental and computing base.

In FIG. 1 shows a structural diagram of the proposed radar, where for simplicity are not shown OPU, current collector, rotation drive and secondary power sources AAK 1, elements of time and angular synchronization.

As can be seen from the structural diagram of the radar, the URS 8 is mechanically connected to AO 2, AK 5 and the antenna NRZ 10, the input-output of the AO 2 is connected to the first input-output of the DOW 3, the second input-output of which is connected to the input-output 1111У 6, the input which is connected to the output of AK 5, and the output to the first input of the UPR 7, the second input of which is connected to the output of the UORT 4, the output to the input of the DOU 3, and the input-output to the second input-output of the UVO 11 and the input-output of the UOK 8 the input of which is connected to the second output C of the NPP 13, the first output of which is connected through the low-frequency current collector to the inputs of the sources of watts of the original AAK 1 power supply, the first input-output of UVO 11 is connected to the input-output of the NRZ 10, and the output is connected to the input of the ATKS 12, the output of which is the output of the radar.

AO 2 is an AFAR with 4 rows, 14 columns and 56 MRPs.

PPU 6 contains one transmitting and, as in the prototype, four receiving channels - the main and three compensation.

 AK 5 consists of three emitters and is located on the back of the AFAR.

UORT is a multifunctional radio navigation complex MRK-32, whose antenna is located on the upper part of AO 2.

AO 2, AK 5, antennas UORT 4 and NRZ 10 are located on a common antenna mast device.

UPR 7 and UVO 11 are made on the basis of modern specialized high-performance electronic computers (computers).

UUOK 8 represents two workstations of the operator RMO, made on the basis of a laptop. One of the RMO is located in the driver’s cab of the vehicle, and the second is remote and can be removed from the radar to a distance of 0.5 km.

The SAES 13 consists of a power take-off generator (HOM), a diesel power station (DES) used as a reserve, and a unit for switching on and distributing primary power.

The proposed radar operates as follows.

The initial linear-frequency-modulated (LFM) probe pulses, amplified by power to the required level, from the PPU 6 enter through the DOU 3 to the transmitting parts of the APM AFAR AO 2, which radiates them into space. In DOU 3, the required amplitude-phase distribution (AFR) of the probe pulses is provided to form a given radiation pattern (BF) of AO 2. The AFR values are calculated in the UPR 7 computer in accordance with the radar survey program in the vertical plane and the carrier frequency of the probe pulses.

The radar signals received and amplified by the receiving parts of the APM AFAR AO 2 are fed to DOU 3, at the output of which radar signals of the main and two compensation receiving channels are generated. The signals of the compensation channels are used in the UPR 7 to compensate for the active interference received by the side lobes of the antenna beam of the main receiving channel.

To compensate for the active interference received by the back lobe of the antenna beam of the main receiving channel, the signals of the third compensation channel, received by AK 5 located on the back side of AO 2, are used.

The signals of the main and three compensation receiving channels through PPU 6, where they are amplified and converted, are digitally fed to the first input of the UPR 7, to the second input of which the signals of the UORT 4 device are received. The result of the initial processing is the automatic detection and measurement of range, azimuth and ( within the range of -10 to 35 °) the elevation angle of objects, auto-compensation of active noise interference, control of AO 2 through DOU 3 and more.

Information about the coordinates of objects from the UPR 7 enters the UVO 11, which implements the formation of object tracks, recognition of their classes, management of the NRZ 10, identification of state recognition signals with the tracks and information pairing through the antenna of the telecode communication channel 12 with consumers of radar information.

UORT 4 provides automatic orientation of AO 2 relative to the direction to the North and the determination of the geographic coordinates of the radar based on the signals of the GLONASS (Russia) and GPS (USA) satellite navigation systems to recalculate the coordinates of the detected objects relative to the location of the radar on the ground.

The coordinates of the objects from the UPR 7 output, tracks and identification marks from the output of the UVO 11 are displayed on the screen of the UOK 8, which is the operator’s workstation, from whose console the radar equipment is controlled and its technical condition is monitored.

URS 9 is an automated hydraulic system with mechanical elements that provides folding (unfolding) AO 2, lowering (raising) and laying the antenna mast device, on which AO 2, AK 5, NRZ 10 and UORT 4 are located, on the vehicle platform and its automatic leveling when deploying a radar.
