Adaptive clutter map detector with a band-selective velocity filter in the multimode radar signal processor using array processing technique

Abstract

A new clutter map detector is designed and implemented using an array signal processor (ASP)-high performance multi-DSP board used for the multimode radar signal processor (MRSP)-for regulating the false alarm due to the strong discrete clutter as well as detecting the slowly moving strong target over the clutter zone. This allows the map parameters to be updated such as input velocity filter coefficients, scale factor, and weighting factor. The band-selective clutter map is available by adapting input velocity filter depending on the various types of clutter and/or target environments. This approach can give high target detectability through on-site adaptation.
