雷达信号处理技术及仿真

Radar signal processing technique and its simulation

在此借助Matlab软件对雷达信号处理过程进行仿真,从仿真图形直观地理解雷达信号处理过程,也体现了Matlab软件在雷达信号处理仿真中的方便、快捷等优点。另外,对当今雷达恒虚警检测技术的现状、不足及其发展动态进行了论述,并通过改进模拟退火算法,提出了一种最优门限恒虚警检测算法。该算法能够在恒虚警检测过程中有效地选取检测门限,提高了雷达系统的恒虚警检测性能,对恒虚警发展具有一定的参考价值。

The process of radar signal processing was simulated by Matlab software, from which the simulation graph can make us have a visualized understanding on the process of radar signal processing, and reflect the convenience and quickness of Matlab software in radar signal processing and simulation. In addition, the current status, shortages and development trend of current radar constant false alarm rate（CFAR）detection technology are elaborated. Through improving simulated annealing （SA）, an optimal threshold constant false alarm rate detection algorithm which can effectively select detection threshold in the process of constant false alarm rate detection is put forward. The constant false alarm rate detection performance of the radar system can be improved, and a certain reference value on the development of constant false alarm rate can be gained.
