| 摘 要： | 针对压缩感知雷达的感知矩阵相干系数随分辨率增加而增大以致不能以大概率对稀疏向量进行完美重构的问题，直接基于原始感知矩阵，提出紧凑感知矩阵追踪(CSMP)算法。该文将CSMP算法应用于十字阵雷达的2维波达方向(DOA)估计并进行了计算机仿真。仿真结果表明与多信号分类(MUSIC)算法，子空间追踪(SP)算法，基追踪(BP)算法和稀疏贝叶斯学习(SBL)算法相比，基于CSMP算法的DOA估计分辨率得到了较大提高。

| Abstract: | In this paper, a novel algorithm named Compact Sensing Matrix Pursuit (CSMP) is proposed to deal with the high coherence problem encountered in the compressed sensing based radar system with high resolution. The CSMP algorithm is applied to the two dimensional Direction Of Arrival (DOA) estimation of cross-array. The simulation results show that the resolution can be increased largely compared with the MUltiple SIgnal Classification (MUSIC) algorithm, Subspace Pursuit (SP), Basis Pursuit (BP), and the Sparse Bayesian Learning (SBL) algorithms. |
