ABSTRACT:
The present invention relates to a method for eliminating range side lobes of a phase modulated radar pulse when compressing the same in the receiver of a radar equipment. The incoming radar pulse is inverse filtered in the receiver by means of two digital filters. After filtering in the first filter the sequence thus obtained is reversed in time and the reversed sequence is again filtered in the second filter so that it is possible to use only stable filters for the inverse filtering.
