In order to solve the problem of increasing complexity and cost of large radar system in flight test,a real-time radar echo simulation system is designed by using digital simulation technology.Aiming at the characteristics that the interference sources of the radar detection space in the application area are multiple and distributed randomly,the simulation system is designed by using the fidelity and real-time performance of the digital simulation technology.The modular design is adopted to design the function models and state models of all the interference sources,which can flexibly configure the target,environment and interference factors of the radar detection space.The test results show that the system has the advantages of strong generality,low cost and flexible operation.The problem of evaluation and verification of the increasingly complex radar system during the flight test is solved.
