METHOD OF RADAR-OBJECTIVE DETECTION OF DANGEROUS OBSTACLES AT LOW-ALTITUDE MISSION OF THE FLIGHTING APPARATUS Russian patent published in 2018 - IPC G01S13/93 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to the field of radar and is intended for use in radar stations (RS) to prevent collisions of lethal vehicles with ground obstacles. Method is based on the fact that a two-line view of the underlying surface along the azimuth is carried out by the beam of the beam at different ranges of range. During the review, the reflected signal is accumulated, threshold processing is performed. When an obstacle is detected, a scan is performed on the elevation angle, find the upper boundary of the obstacle, calculate the excess of the aircraft over the obstacle and compare with the permissible excess.

EFFECT: expansion of the range of azimuth angles, in which the search for dangerous obstacles is performed at low altitude flight of an aircraft, and also while maintaining a short time of the survey.
