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 have proposed 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 number of clutter and its center frequencies utilizing AR (Auto Regressive) coefficients by computer simulations. |
