ABSTRACT.
Radar system simulation is a combination of digital simulation technology and radar technology. At present, the controllability, repeatability, safety, economy, non-destructive characteristics of computer simulation technology are used for simulation and effectiveness evaluation, which is an important method in the field of radar and electronic countermeasures. This article will take the pulse Doppler radar system as an example, and simulate it by using MATLAB add-on virtual reality. The paper first discusses the basic structure of the pulse Doppler radar system and the pulse compression radar system, and then discusses its clutter environment modeling. The orthogonal Gaussian noise is used to generate Rayleigh clutter to simulate the clutter environment. Discussed and analyzed the radar system’s waveform, detector, signal processor model, CFAR, and detector model, and took pulse Doppler radar as an example to establish a radar module library in virtual reality to facilitate the modeling of the radar system and simulation. Finally, it is compared with the simulation of radar system using MATLAB language directly, in order to explore the method of modeling and simulation of radar system.
