Abstract(in English) | A clutter suppression method using time-varying transversal FIR filters applicable for search radar with staggered PRF (Pulse Repetition Frequency) operation has been presented. We have proposed the suppression filters with cascade connection as an effective method at staggered PRF. In this method, clutter center frequencies are estimated utilizing AR (Auto Regressive) coefficients. When clutter center frequency is larger than half of PRF, the clutter suppression performance is degraded by the estimation error. In this report, we propose a method to secure the clutter suppression performance and show its effectiveness by computer simulations. |
