Multiple Targets Localization in Sparse Representation-Based Frequency Diverse Array MIMO Radar
摘要
Abstract
For the frequency diverse array(FDA)multiple-input and multiple-output(MIMO)radar,a target localization algorithm in sparse signal representation perspective is presented.Firstly,the characters of the MIMO radar and FDA are reviewed,then the properties of the FDA MIMO radar are studied,that is,it not only owns the merits of the MIMO radar,but also can sense the range information of the targets.Its re-ceiving mathematical measurement is also modeled,and the target localization problem is described as a cost function under the sparse representation framework.Finally,the angle and the range of the targets are esti-mated by mapping the non-zero element indexes of the sparse vector which is obtained by solving the cost function using existing convex tool.Compared with the existing classic MUSIC algorithm,the proposed algo-rithm can achieve better localization performance.The computer simulation results demonstrate the effective-ness of the algorithm.关键词
