Design And Implementation Of Over-clutter Target Detection On A Radar Signal Processor

The design, regulation and combined adjustment of radar signal processor software, including over-clutter target detection, clutter map, and CFAR are presented in this paper, based on a radar signal processor project.The paper introduces the composing and application of over-clutter target detection firstly, then introduces the principle of several typical methods of CFAR, including cell-averaging CFAR detector,greatest of-CFAR detector etc, and then compares the performance of the several typical methods. The principle and implement of clutter map are discussed in this paper.Using the signal processing hardware platform available, the related signal processing software is designed and the above function is implemented according to hardware platform of the signal processor. Assembly code optimization of digital signal processor (TS201) is introduced in the paper. This paper also introduces the principle and implement of the binary integration, the performance of which are studied and simulated.At last, the methods of system testing are introduced based on its engineering realization of hardware and software. The result is presented in the paper. It's proved by the result that this system can reach a good effect to detect targets in clutter.
