摘　　要：本文将TM-CFAR与另外两种在工程实践中广泛应用的算法GO-CFAR和OS-CFAR进行了matlab仿真分析,尤其是针对杂波边缘和多目标场景下,对TM-CFAR的检测效果进行了分析。在DSP中实现TM-CFAR,统计各种实现方法的运算时间。作为进一步提升效率的对比实验,进行了开启O3优化和不开启O3优化的时间统计,针对前后时间变化大的情况,进行了简要的分析,给出了TM-CFAR实现效率较高的方法。In this paper,TM-CFAR and another two widely used CFAR methods,GO-CFAR and OS-CFAR,were simulated and analyzed through matlab.Detection performance of TM-CFAR was analyzed,especially around clutter edges and multiple targets situation.Then,TM-CFAR was realized in DSP to conduct statistical analysis on calculation time of various methods.For further comparison on efficiency increasing results,the experiments were set up for time statistics on calculation with 03 optimization and without 03 optimization.Results showed that calculation time difference was large,and basic analysis on this result was also discussed in the paper,with a method proposed for TM-CFAR efficiency improvement in DSP.
