摘要
在宽频段内多信号多参量联合估计已成为许多研究课题,例如,未知辐射源识别.有源对消等等的重要研究内容.信号频率与二维到达角、二维到达角与极化的联合估计已开展研究,但信号频率、二维到达角和极化联合估计的研究尚未见报导.本文提出了利用交叉偶极子平面阵和ESPRIT算法实现频率、二维到达角和极化联合估计的新方法.分析了算法结构,计算机模拟结果证实了算法的有效性.
It is very important in many study fields to estimate multi parameters of multi signals in broad band,such as recognizing of unknown emitting sources,active canceling and so on.The problems of estimating signal frequency along with DOA and DOA along with polarizations have been studied.But it hasn't been reported the method of joint estimating of frequency,DOA and polarizations yet.A new method that joint frequency,two dimensional arrival angles and the polarizations estimation of incoming narrow band signals use the ESPRIT algorithm and a square array of crossed dipoles is proposed.
