摘要
极化信息同雷达信号中的幅度、相位、频率、波形一样,是雷达信号的一个重要参量。不同的辐射源,其极化方式也不同,测量电磁波信号的极化方式对辐射源信号分类、识别都具有重要意义。基于此,提出了用一对正交天线来测量辐射源的极化,通过对此方法进行Matlab仿真实验,并分析实验结果,证明了理论模型和算法的正确性,同时阐述了此方法的优缺点。
Polarization information, like amplitude, phase, frequency, and wave shape, is an important pa- rameter of radar signals. Different emitters correspond to specified polarization states. The measurement of polariza- tion styles has great significance to the classification and identification of emitters. In this paper, the orthogonal po- larization antenna method is introduced to measure the polarization of the EM wave. The method is simulated by Mat- lab programs. Simulation results demonstrate the correctness of the theoretical model and the algorithm. The advan- tages and disadvantages of the method are presented.
