Abstract: For more convenient application of radar echo signal simulation to practice，a software implementation approach of real-time radar echo signal simulation is proposed.Firstly，in the light of the principle of radar signal receiving and processing，radar work mode and battlefield environment are modeled and simplified，and radar echo signal is simulated by software.Secondly，by using of the convenience of software implementation，some interactive interfaces are designed to receive the radar work status adjustment and the simulated battlefield environment modification.In this way，dynamic radar echo signals under varied environment are produced in real-time，thus the flexibility and universality of radar echo signal simulation are improved.Simulation results validate the applicability and effectiveness of the presented method.
