Abstract

In a method of suppressing jammer signals in the received signal of radar antennas of HPRF applications (such as pulse Doppler radar systems) by means of Fast Fourier Transformation and side lobe cancellation, the receiving radar antenna has a sum channel, a difference channel and an auxiliary channel. The received signal is first transformed in the sum, difference and auxiliary channels from the time domain into the frequency domain using a Fast Fourier Transformation (FFT). Subsequently, the the jammer signal, particularly the side lobe jammer, is suppressed in the frequency domain by means of side lobe cancellation.
