摘要:
针对双基地MIMO雷达三维空间目标参数估计问题,建立非均匀线型发射阵列和非均匀L型接收阵列的信号模型,并提出基于平行因子分析的目标收发角和多普勒频率联合估计算法。该算法首先利用平行因子分析和四线性交替最小二乘算法计算得到目标导向矩阵,进而构造虚拟导向矩阵并进行去冗余和降噪处理,最后通过Root-MUSIC算法估计出目标三维收发角和多普勒频率。仿真实验表明,与传统算法相比,所提算法实现了孔径的高效扩展,提高了参数估计精度,降低了系统配置需求。
Abstract:
Aiming at the problem of three-dimensional (3-D) space target parameter estimation for bistatic MIMO radar, a signal model of non-uniform linear transmitting array and non-uniform L-shaped receiving array was established. And a joint estimation algorithm of target transmit-receive azimuths and Doppler frequency was proposed, which was based on parallel factor analysis. Firstly, the target steering matrices were calculated by the parallel factor analysis and quadrilinear alternating least squares (QALS) algorithms. Then, the virtual steering matrices were constructed and the processing of de-redundant and noise reduction is performed. Lastly, the target 3-D transmit-receive azimuths and Doppler frequency were estimated by the Root-MUSIC algorithm. Simulation experiments demonstrated that, compared with traditional algorithms, the efficient expansion of the aperture was attained by the proposed method and the accuracy of parameter estimation was improved while the system configuration requirements were reduced.
