【摘要】 本文结合某型号雷达,对该雷达信号处理机的超杂波检测、杂波图和恒虚警处理(CFAR)等软件进行设计、调试。论文首先论述了超杂波检测的组成和工作原理,介绍了几种典型的恒虚警处理方法,如单元平均(CA-CFAR)、单元平均选大(GO-CFAR)检测器等,并且分析比较了这几种恒虚警方法的性能;分析了杂波图的实现方法。利用现有的信号处理硬件平台,设计了超杂波检测的DSP处理软件。本文还介绍了数字信号处理器(TS201)的汇编语言的优化方法,论述了恒虚警结果的二进制积累方法,并且仿真分析了二进制积累方法的检测性能。最后,在软硬件实现的基础上,详细的介绍了系统性能测试的方法,给出了测试结果。结果表明,系统可以有效的实现目标检测。更多还原

【Abstract】 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.更多还原
