摘要
建立了考虑目标电磁散射特性时频变化的回波仿真模型,给出了目标电磁散射特性对回波在方位向和距离向的调制效果,并对典型目标进行了回波仿真和成像处理,验证了目标电磁散射特性对高分辨率星载SAR图像仿真的影响,并提出了高分辨率星载SAR图像仿真方法改进的方向。
The raw echo generation model is established considering the varying target electromagnetic scattering characteristics,and the module effects on azimuth and range direction are also presented.The echo generation and imaging results for typical target demonstrate the effectiveness of the proposed analysis method.Further improvement direction is put forward for the high resolution spaceborne SAR image simulation.
