摘要

摘要: 針對(duì)收發(fā)分置多輸入多輸出(MIMO)雷達(dá)發(fā)射端和接收端均存在位置誤差的問(wèn)題，該文提出一種基于雜波回波的收發(fā)陣列位置誤差聯(lián)合校正方法。該方法以最小化雜波回波數(shù)據(jù)的重構(gòu)均方誤差為準(zhǔn)則，在雜波散射系數(shù)l1范數(shù)稀疏約束下，利用雙迭代與凸優(yōu)化方法對(duì)雜波散射系數(shù)和陣列位置誤差參數(shù)進(jìn)行聯(lián)合優(yōu)化求解，最終完成了對(duì)收發(fā)陣列位置誤差的同時(shí)估計(jì)與校正。仿真實(shí)驗(yàn)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.
