Abstract: According to the characteristics and key points of the course of electronic system modelling, simulation and evaluation, the radar signal and data processing digital simulation system is introduced in the course. The constructions and functions of the simulation system are provided to illustrate its advantages during the implement of the course. At the same time, the modularization design makes the knowledge points, the practice case and the scientific research can be updated timely in the simulation system and introduced to the course. Then, the course can be continual improvement. Educational practice shows that the implementation of the simulation system can improve the comprehension of radar system for students so that the students can well master the knowledge.
