摘要

摘要: 针对收发分置多输入多输出(MIMO)雷达发射端和接收端均存在位置误差的问题，该文提出一种基于杂波回波的收发阵列位置误差联合校正方法。该方法以最小化杂波回波数据的重构均方误差为准则，在杂波散射系数l1范数稀疏约束下，利用双迭代与凸优化方法对杂波散射系数和阵列位置误差参数进行联合优化求解，最终完成了对收发阵列位置误差的同时估计与校正。仿真实验表明了所提算法的有效性。

Abstract: The issue of position error estimation for transmit and receive array of a bistatic Multiple-Input Multiple-Output (MIMO) radar is investigated, and an algorithm for the joint estimation based on clutter echo is proposed. The algorithm is based on the criterion of minimizing the reconstruction mean-square error of clutter echo under the restraint ofl1-norm of clutter coefficient. An alternately iterative and convex optimization algorithm is adopted to complete the estimation of clutter scattering coefficients and the position error of both transmit and receive arrays. The simulation results indicate the effectiveness of the proposed algorithm.
