METHOD FOR SUPPRESSING PASSIVE RADIO INTERFERENCES

The proposed method for suppressing passive radio interferences consists in filtering the reflected radio signals, which propagate in signal bursts with the same frequency, by doppler filters, determining the ratio between the amplitude of the output signal of each filter and the average amplitude d...

Zusammenfassung:	The proposed method for suppressing passive radio interferences consists in filtering the reflected radio signals, which propagate in signal bursts with the same frequency, by doppler filters, determining the ratio between the amplitude of the output signal of each filter and the average amplitude determined by the output signals of the other filters, and isolating the filter output signals for which the said ratio exceeds the threshold value. The average amplitude of the filter output signals is determined by the maximal amplitudes of signals in the bursts that are received in the preceding and in the next time intervals relative to the analyzed signal.
