| 摘 要： | 本文提出了一种存在幅相误差下的双基地MIMO雷达角度估计方法.利用三次迭代最小二乘算法估计存在幅相误差下的收、发阵列流形,根据信号子空间和噪声子空间的正交性,无需幅相误差的任何信息,采用MUSIC-like算法得到目标的DOD和DOA,且角度自动配对.针对MIMO雷达孔径扩展的特点,分别通过第一个发射阵元和第一个接收阵...

| Abstract: | An algorithm for joint estimation of angle and gain-phase error for bistatic MIMO radar is presented.Array manifolds associated with transmit and receive arrays in the presence of gain-phase errors can be obtained by tri-iterative least-square method.According to the orthogonality of the signal-and noise-subspace,the direction-of-arrivals(DOAs) and direction-of-departures(DODs) of targets are estimated by exploiting MUSIC-like algorithm without any priori knowledge of gain-phase error,and automatically pair... |
