摘要
目前,在雷达系统海面回波信号的模拟中,仅仅是根据距离和相对运动速度等参数,建立起目标的回波模型,但实际雷达在海面探测到的回波不仅有舰船目标,还有海浪的电磁散射,探测环境复杂。利用复合电磁场景模拟计算技术计算出低海况下目标与海面耦合下的散射场景,实现某些典型军事目标和背景环境雷达反射截面积(Radar Cross Section,RCS)预估和成像、目标高分辨距离像(High Resolution Range Profile, HRRP)成像与逆合成孔径雷达(Inverse Synthetic Aperture Radar,ISAR)成像,并对仿真结果进行了分析。
At present,in the simulation of sea surface echo signals in radar systems,target echo models are established only based on parameters such as distance and relative motion speed.However,in reality,the echoes detected by radar on the sea sur‐face not only include ship targets,but also electromagnetic scattering of waves,resulting in complex detection environments.This article uses composite electromagnetic scene simulation calculation technology to calculate the scattering scene of targets and sea surface coupling under low sea conditions,achieving radar cross section estimating and imaging,high-resolution one-dimensional range profile imaging and inverse synthetic aperture radar imaging of certain typical military targets and background environ‐ments.Simulation results of the target were analyzed.
