摘要

摘要: 传统MIMO雷达为了获得准确的距离信息不仅需要引入转移矩阵，而且需要积累更多的快拍数。针对该问题，该文提出了基于稀疏迭代的频控阵MIMO雷达多维信息（距离、角度和幅度）估计方法，该方法利用频控阵MIMO的发射导向矢量不仅与目标的方位角有关，同时也与目标的距离有关这一特性，通过优化加权lq范数（0 q 1）的目标函数，采用稀疏迭代优化获取目标的距离、角度和幅度信息。该方法仅需单次快拍，并在每次迭代中求解到了目标的多维信息，故不需借助优化工具获得目标信息。仿真显示，相比DAS，IAA和IAA-R，该方法在有效减少快拍数和处理数据的同时，获得了高分辨率的目标距离、角度和幅度估计性能。

Abstract: To accurately identify the range of each target, traditional Multiple-Input Multiple-Output (MIMO) radar techniques not only require designing a shift matrix to describe different range bins but also a large number of snapshots.To alleviate this problem, a multidimensional parameter estimation method based on sparse iteration is proposed for a MIMO radar with Frequency Diverse Array (FDA).The FDA-MIMO radar uses small frequency increments across the array elements, and its transmit steering vector is a function of both range and angle.On the basis of the feature of the FDA-MIMO radar, we consider a weighted lq (0 q 1) minimization problem that is solved using a sparse iterative algorithm.Finally, the target parameters (the amplitude, range, and angle) are obtained using a single snapshot.Moreover, numerical simulations are used to demonstrate the superior performance of the proposed method compared with those of DAS, IAA, and IAA-R.
