Calibration for Low Frequency UWB SAR Based on Time Domain

摘要

摘要: 低頻UWB SAR系統(tǒng)校準的關鍵問題是獲得定標體精確的散射特性和建立合適的信息處理模型。本文利用MOM和漸近波形估計（AWE）方法得到隨頻率和方位角變化的角反射器RCS，建立了基于時域聚焦算法的校正模型，最后利用計算機仿真驗證了該方法的有效性。

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.
