SMALL-SIZE MULTI-MODE ON-BOARD RADAR SYSTEM FOR EQUIPPING PROMISING UNMANNED AND HELICOPTER SYSTEMS Russian patent published in 2019 - IPC G01S13/90 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to radar ranging, in particular, to radar systems. Technical result is achieved due to integration of digital devices included in the system (frequency synthesizer, synchronizer, receiver, central computer with high efficiency, high-speed data transmission interfaces) into a single macro module, as well as the presence of four receiving channels with difference radiation patterns in the inclined and azimuthal planes, total and compensated, using corresponding methods of monopulse direction finding, which increases accuracy and reliability of measurement of angular coordinates in azimuth and elevation angle. In the proposed system, probing signals are generated with different types of modulation, an inter-period spectrum expansion method is used, which enables to increase the range resolution using narrow-band signals with a known order in a pulse train and rapid tuning of frequencies from pulse to pulse.

EFFECT: design of a small-size multi-mode on-board radar system for equipping advanced unmanned and helicopter systems in order to perform monitoring of the earth's surface during search and rescue and special operations, as well as protection of coastal water area.
