摘要 针对LFM信号,利用分数阶傅里叶变换构造了一种新的空间极化时频分布:提出了基于L型矢量阵元阵列的二维到达角和极化联合估计算法。理论分析和仿真实验结果都表明,在低信噪比下该方法比已有的极化和到达角联合估计算法具有更好的性能。 A new spatial time-frequency distribution of polarization is constructed using fractional Fourier Transform for LFM signals, A novel algorithm of joint two-dimensional and polarization estimation is proposed based on the vector sensor array of L mode. Theoretical analysis and computer simulation demonstrate the efficacy in the lower signal noise rate.
