摘　　要：Simulink具有丰富的标准模块库,但并非所有仿真系统都可以通过标准模块搭建,其自定义模块实现了Simulink的功能扩展。通过研究S-函数的工作原理,介绍了S-函数创建和封装用户自定义模块的基本算法,利用S-函数M文件基本的框架资源,编写了伪随机码信号的M源文件。通过分析伪码调相信号的信号特性,实现了伪码调相连续波信号的快速生成。仿真结果表明,自定义模块扩充了Simulink的仿真功能,提供了一种新的雷达信号源产生方法,为工程人员的使用与研究提供极大方便。Simulink has a rich library of standard blocks,but not all of the simulation system can be built through the standard block,its custom block implements the function extension of Simulink.By studying the working principle of S-function,this paper introduces the basic algorithm of the S-function to create and encapsulate the user-defined block,and uses the basic framework of the S-function to write the M resource file of the pseudo-random code signal.Through the analysis of signal characteristics of pseudorandom code phase modulation signal,realize the rapid generation of pseudorandom code.The simulation results show that the custom module extends the simulation function of Simulink,a new method for generating radar signal source is provided,which can provide great convenience for the use and research of engineering personnel.
