论文摘要
在共凝结的压缩感测MIMO雷达中，测量矩阵由天线放置指定。为了确保可接受的恢复性能，该测量矩阵应满足某些特性，例如小连贯性。文献中的先前工作经常采用随机放置算法来优化天线位置的先前分布。这些算法的性能是次优的，因为它们可以通过消耗轻松增强。在本文中，我们建议一种迭代天线放置算法，该算法确定天线位置。所提出的算法在发射和接收阵列上共同定位天线元件，以使所得测量矩阵的相干性最小化。数值模拟表明，即使在消耗后，提出的算法也明显优于基准。
In colocated compressive sensing MIMO radar, the measurement matrix is specified by antenna placement. To guarantee an acceptable recovery performance, this measurement matrix should satisfy certain properties, e.g., a small coherence. Prior work in the literature often employs randomized placement algorithms which optimize the prior distribution of antenna locations. The performance of these algorithms is suboptimal, as they can be easily enhanced via expurgation. In this paper, we suggest an iterative antenna placement algorithm which determines the antenna locations deterministically. The proposed algorithm locates jointly the antenna elements on the transmit and receive arrays, such that the coherence of the resulting measurement matrix is minimized. Numerical simulations demonstrate that the proposed algorithm outperforms significantly the benchmark, even after expurgation.
