Abstract: The digital simulation of radar and the establishment of radar simulation libraries has become research hot spot in radar field in recent years. This paper mainly focuses on phased array radar system simulation. According to the composition and principle of phased array radar, it establishes the simulation model and mathematical model of phased array radar. Then, the paper does simulation and research on phased array radar system by choosing Simulink as the simulation platform. The simulation module mainly includes the antenna module, the signal environment module, the signal processing module and GUI man-machine interface module. Eventually it generates radar sub-libraries and forms phased array radar system, which lay the foundation for follow-up phased array radar study.

Key words: radar, phased array, signal processing
