FIELD: radio engineering; radar systems for detecting obstacles.
SUBSTANCE: purpose of invention is to increase the probability of detecting objects. It is achieved through a method of processing a digital radar signal, characterized in that virtual antenna arrays are formed based on a MIMO structure, while providing high resolution in the azimuthal plane, which allows the detection of objects on the range-azimuth map in addition to the method of object detection on the distance-speed map. Thus, the results of detection of objects with selection by range, speed and azimuth are combined. Also proposed is a radar with the possibility of implementing the proposed method for processing a digital radar signal. The proposed technical solution provides the detection of objects on the range-speed and range-azimuth, which allows you to combine the advantages of selecting objects according to the parameters range, speed and azimuth.
EFFECT: increase in the probability of detecting objects.
