摘要

Method of formation of the null of passive interference and means for its embodiment relate to the radar-location. The formation of the null of passive interference within wide borders and improvement of uniformity of the amplitude-frequency characteristic in this band is provided for that Doppler filtration of every frequency pack of echo-signals is carried out by such number of Doppler filters, at which the ratio of frequency of recurrence of echo-signals in frequency pack to the number of Doppler filters in this frequency pack remains constant for all frequency packs of echo-signals, and in addition the blanking of signals of those Dopplerfilters is carried out, which at various frequencies of recurrence cover the same frequency domain within the null of passive interference.
