Abstract

This study considers the process of detecting a low-altitude, low-speed air object in the presence of ground clutter. The principal hypothesis assumes that improving the method could make it possible to increase the signal/noise ratio.

A method has been improved for detecting a low-altitude, low-speed air object in the presence of ground clutter using a synchronous multi-radar system, which, in contrast to known ones, allows for the following:

– a synchronous survey of the airspace in azimuth and range by two radars by emitting mutually orthogonal probing signals;

– forming signals reflected from the air object at the output of the radar receivers;

– incoherent, joint signal processing in a synchronous multi-radar system from two survey radars;

– coordinated filtering of received signals;

– formation of Doppler channels;

– equalization by delay time and Doppler frequency;

– formation of an additive processing channel where incoherent summation of signals is carried out and formation of air object detection marks in the additive channel;

– formation of a multiplicative processing channel where multiplication of signals is carried out and formation of air object detection marks of the multiplicative channel;

– combination of air object detection marks of the additive and multiplicative channels and formation of final detection marks.

An experimental study was conducted on the detection of a low-altitude, low-speed air object. The use of a synchronous multiradar system made it possible to increase the signal/noise ratio by 4 times. Additional multiplicative signal processing provides an increase in the signal/noise ratio and improves the discrimination of the signal from the air object in the presence of ground clutter
