SIDE-LOOKING RADAR OF EARTH WITH SYNTHESIS OF ANTENNA APERTURE AND ULTRA HIGH RESOLUTION

摘要

FIELD: radio engineering.;SUBSTANCE: in the proposed radar the output at least of one receiving antenna having the possibility of changing the aperture is connected to the first input of radio-frequency low-noise amplifier (LNA) the output of which is connected to the first input of analogue-to-digital converter (ADC); the first output of synchronisation module (SM) is connected to the second input of LNA and the second input of ADC the first information data bus of which is connected to the first information inputs of software-and-hardware complex (SHC) of digital data processing, recording, control and communication in real-time mode, which is connected with its first output to the third LNA input; the second output of SHC is connected to the first input of video pulse generator the output of which is connected to the output with lead-out at least of one transmitting antenna having the possibility of changing the aperture; the second and the third SM outputs are connected to the first and the second control inputs of SHC respectively, the first control data bus of which is connected to control inputs of ADC, the third input of which is connected to the fourth SM output connected with the fifth output to the second input of video pulse generator; the sixth SM output is connected to the first input at least of one spatial movement sensor (SMS) of radar, the output of which is connected to SM input and the second information data bus of which is connected to the second information inputs of SHC the second control data bus of which is connected to SM control inputs, and the third control data bus is connected to control inputs at least of one SMS; at that, SHC has the possibility of transmitting the data via the third information data bus to digital radio channel.;EFFECT: improving range of coverage and resolution capability of radar, providing operating stability and improving informativity.;9 cl, 1 dwg
