| 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. Because such a clutter suppression filter has no method controlling filter order automatically, order of every filter needs to be determined beforehand. Therefore, we propose a method for determining the overall filter order by comparing the power ratio of the input and output signal of each first-order filter with cascade connection. In this report, we evaluate the performance of the proposed methods with an estimation process of the clutter center frequency using the coefficients of auto-regressive model by computer simulations. |
