RADAR SYSTEM OF REMOTE EARTH SENSING Russian patent published in 2013 - IPC G01S13/90 

FIELD: radio engineering, communication.

SUBSTANCE: method is carried out by inclusion of an unmanned aircraft, a low-speed radio channel of data transfer into the composition of the structural circuit of the available radar system and by variation of the mode of operation of the generator that generates signals with linear-frequency modulation with a modulation period equal to the interval of antenna aperture synthesising, which simultaneously performs functions of the clock pulse oscillator of the wide-band carrier of the radar data transfer channel. The proposed system makes it possible to produce radar data from a board segment of the synthetic aperture radar NI along a noise-immune low-speed communication channel, to process them and to produce radar images with the required resolution in the real time mode.

EFFECT: improved noise immunity relative to active noise.
