| 摘 要： | 低频UWB SAR系统校准的关键问题是获得定标体精确的散射特性和建立合适的信息处理模型。本文利用MOM和渐近波形估计（AWE）方法得到随频率和方位角变化的角反射器RCS，建立了基于时域聚焦算法的校正模型，最后利用计算机仿真验证了该方法的有效性。

| Abstract: | The key problem of calibration for low frequency ultra wide band synthetic aperture radar system is the acquisition of the scattering information of calibrators and suitable signal processing model. In this paper, the RCS of trihedral triangle reflector changing with the frequency and aspect angle is obtained using methed of moment and AWE method, and the calibration model is proposed based on time domain. The computer simulation is used to verify this calibration method, and result is agreed with the theory analysis. |
