METHOD FOR FRONTAL EARTH SURFACE APERTURE SYNTHESIS WITH EXCLUSION OF BLIND ZONES IN FRONT ZONE USING MULTI-POSITION RADAR SYSTEM Russian patent published in 2015 - IPC G01S13/90 

FIELD: physics, navigation.

SUBSTANCE: invention relates to multi-position on-board radar stations and can be used to form a radar image of an area of the earth's surface under surveillance. Using anterolateral scanning, the frontal area of the earth's surface is synchronously irradiated with probing signals using two antennae on-board an aircraft, wherein receive/transmit positions, depending on the extent of the irradiated frontal area of the earth's surface, are at a distance d from each other such that irradiated neighbouring zones overlap and reflected signals, which are received by the two antennae on-board each of N aircraft, directed towards a given direction for left and right side anterolateral scanning, accumulate the reflected signals, and processing thereof results in two high-resolution radar images from the irradiated areas of the earth's surface in the direction of irradiation of the two antennae by using an aperture synthesis algorithm, after which on one of the N aircraft, radar images are synthesized via a communication channel from each of the N aircraft, thereby obtaining a high-resolution radar image in real time in the front zone, excluding blind zones.

EFFECT: high angular coordinate resolution.
