摘要
阐述不同波段和束宽下,散射点偏离光束中心对成像的影响,主光束边缘扩展目标散射点径向距离分布的变化特征。提出利用散射点的角度测量信息来补偿速度修正。仿真验证该方法的有效性。
This paper analyzes the influence of the scattering point deviating from the beam center on imaging under different wavelength bands and beam widths, and the change characteristics of the radial distance distribution of the extended target scattering point at the edge of the main beam. It is proposed to use the angle measurement information of the scattering point to compensate for speed correction. The method was verified by simulation.
