A design method of clutter suppression filters with cascade connection using offset of zeros for staggered PRF

Abstract

In search radar with staggered PRF (Pulse Repetition Frequency), a clutter suppression method to use time-varying filters with cascade connection has been presented. However, the suppression performance degrades in the case dig one frequency of zeros with filters coincides others at least. In order to overcome this problem in this report, we propose a design method of clutter suppression filters with cascade connection using offset frequency of zeros.
