A Modified Method for Radar Clutter Recognition Based on a Truncation Set

Abstract

Abstract-his paper is concerned with the recognition of radar clutter. First a recognition method based on α truncation set is introduced. The method is efficient but inconvenient in practical application for the optimal α is difficult to choose. Then a modified method is presented. It makes use of more information of clutter distribution PDFs by defining another kind of α truncation set. As a result, the optimal α is a certain value, making it more convenient for practical application. The simulation and comparisons made at the end show that the modified method has good performance.
