摘要
针对雷达动目标的全极化高分辨信息的获取问题,建立宽带极化雷达的信号模型,分析对应的匹配滤波处理算法。对时/频域加窗的效果进行比较,提出了实用的窗函数选择方法。分析正负线性调频信号对高速运动目标的同时极化测量性能,提出对高速运动目标的极化——一维距离像联合识别方法。仿真结果证明了所此方法的有效性。
Aiming at acquisition of radar moving target full-polarization high resolution information,signal model of wideband polarization radar and corresponding match filter algorithm is established.Meanwhile,window method in time domain and frequency domain is compared and a practical window method is proposed.After that,the performance of moving target polarization measurement through wideband up and down chirp signals is analysed and co-identifying method using both polarization and range profile information is proposed.At last,algorithm validity is proved by computer simulations.
