摘要
针对相参雷达接收机的主要工作原理,运用数字信号处理理论和Matlab软件研究相参雷达接收机的建模与仿真问题。通过对相参雷达接收机的天线模型、回波信号模型、噪声模型进行建模并对同步检波处理、动目标检测、恒虚警检测处理进行分析,实现相参雷达接收机的相干视频模拟。用Matlab对某相参雷达接收机进行仿真,得到接收系统中各个处理点上的具体信号形式,满足对相参雷达接收机仿真要求。
This paper investigates modeling and simulation of the coherent radar receiver based on MATLAB and theory of digital signal processing, according to the theory of coherent radar receiver. With the analysis of the synchronous detection, moving target detection and constant false alarm rate detection, we realize the coherent video simulation based on the modeling of the echo signal, antenna and noise of correlative radar receiver. A coherent radar receiver system＇s simulation with MATLAB shows it meet the requirements.
