Abstract：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‐func‐tion ,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 sig‐nal 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 ra‐dar signal source is provided ,which can provide great convenience for the use and research of engineering personnel .
