Design of Radar Training System Based on Embedded Simulation

The technology and prospects of embedded simulation was introduced. The combine embedded simulation and radar training system make up of simulation training system that can embed in mechanical scanning radar. The structure and function of embedded simulation radar training system were introduced. The method and model of radar video echo were studied, which included target echo, ground clutter, sea clutter, weather clutter, active jamming signal and intemal noise of the radar＇s receiver. The mathematical model was used to calculate the intensity, azimuth, distance of echo characteristic and produce simulative echo data according to state setting parameter by modulating actual echo. The training system can respond signal processing and anti-interference operating. By simulating video echo the image of radar display showed that simulative echo had high fidelity and could be identified by Radar terminal.
