Results of the experimental study of echo burst spectra at the output of a moving target indication system of two-coordinate radars of the Utyos and Lira series are given. A method for additional spectral processing of echo bursts at the output of a moving target indication system is considered, which allows the noise immunity of these radars to be improved. The test results of the radar, modernized according to the proposed method, have shown that a stream of the clutter coordinate points, entering for trajectory processing, decreases by a factor of 10-30.
