摘要

针对空时互质采样下频率和波达方向（DOA

direction-of-arrival）稀疏联合估计中存在的二维栅格失配问题，提出一种栅格失配目标下的频率和 DOA 联合估计方法。首先对入射信号做空时互质采样，建立虚拟满阵下的二维稀疏恢复模型，然后在以上模型中引入频率栅格失配误差项和角度栅格失配误差项进行二维修正，并给出一种改进的贪婪算法，通过对谱泄露变量联合求解来得到二维栅格失配误差项，最终将栅格失配目标校正到精确位置上。该方法不仅可以提高空频域上的自由度（DOF

degrees of freedom），而且在降低运算量的同时改善了频率和DOA联合估计的精度。仿真结果验证了方法的正确性。

Abstract

A method of joint frequency and direction of arrival (DOA) estimation using spatial-temporal co-prime sam-pling with off-grid sources was proposed to solve the problem of two-dimensional (2D) mismatches of signals.Firstly

the received signal was sampled by spatio-temporal co-prime sampling technique to construct 2D sparse reconstruction model with the filled coarray.Then the frequency mismatch term and angle mismatch term were incorporated into the re-ceived data model.Based on the above modified model

an improved greedy algorithm was presented to obtain the fre-quency mismatch and angle mismatch by estimating the spectrum leakage terms jointly.So the 2D off-grid sources can be corrected to accurate positions.The method can increase the degrees of freedom (DOF) in the space-frequency domain.Moreover

the method has reduced the amount of computation

and it can improve the frequency and DOA estimation accuracy in the meantime.Simulation results demonstrate the correctness and effectiveness of the proposed approach.
