METHOD FOR DETECTING SMALL-SIZED AERIAL OBJECTS AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2022 - IPC G01S13/52 

FIELD: radio location.

SUBSTANCE: inventions relate to the field of radio location and can be used in radio location stations (radars) for detecting small-sized aerial objects (targets) moving along a rectilinear trajectory in conditions of interference. The stated result is achieved by increasing, at the second stage of detection, the time of non-coherent multi-angle integration of signals exceeding a lower level threshold at the first stage of detection. Long-term multi-angle integration at the second stage of detection is therein implemented using Hough transforms, and the results of multi-angle integration are compared with the threshold of the second stage of detection, followed by making a decision on the detection of the target with the simultaneous formation of the track thereof.

EFFECT: increase in the detection range and the distance of track initiation both for low-speed and hyper-speed small-sized targets in conditions of interference.
