中文摘要:
      针对双基地多输入多输出(MIMO)雷达收发角联合估计问题,利用信号的循环平稳特性,构造宽带循环平稳信号下接收数据的循环自相关矩阵。对矩阵进行特征值分解,利用MUSIC, ESPRIT等空间谱估计算法估计出信号的收发角。宽带信号能够携带更多的信息量,利于不断增加的实际需求,而信号的循环平稳特性能够很好地抗干扰以及消除高斯噪声带来的影响。实验仿真结果表明,算法在宽带循环平稳信号下具有良好的角度估计性能。
英文摘要:
      Focused on the Direction Of Departure(DOD) and Direction Of Arrival(DOA) estimation of bistatic Multiple Input Multiple Output(MIMO) radar, an estimation method is presented by using wide-band cyclostationary signal. Firstly, an autocorrelation matrix of receiving wide-band cyclostationary signals is constructed. And then eigenvalues of the matrix are decomposed. At last, DOD-DOA are estimated by spatial spectrum estimation algorithm such as MUSIC algorithm or ESPRIT algorithm. Wide-band cyclostationary signal can carry more information, which is increasingly important, and its cyclostationary property restrains Gaussian noise as well as interference from different frequencies effectively. The result of simulation shows that the method has good angle estimation performance with wide-band cyclostationary signals.
