The propagation effect of electromagnetic waves has a significant impact on the detection performance and parameter selection of surface radars.Based on the parabolic equation model,radar echoes are used to sense the current atmospheric environment and evaluate the current atmospheric wave propagation performance.The radar parameters are optimized to form real-time matching between environment-task-parameters in the radar system to enhance the target echo intensity,expanding the radar detection coverage,which is of great significance to the research and design of OTH radars.
