摘 要: | 基于频率选择表面,提出了一种毫米波压缩感知成像方法。通过在频率选择表面单元中加载开关二极管,并随机控制它们处于开/关状态,设计了一种可随机切换的新型毫米波成像掩膜板。通过将这种随机掩膜板放置于毫米波天线上,能够构造出相应的随机测量矩阵并获取足够多的有效测量次数。利用恢复重构算法进行了成像仿真验证,结果证实了所提方法的可行性。

Millimeter wave compressed sensing imaging based on frequency selective surface |
| |
Abstract: | A method of millimeter wave compressed sensing imaging based on frequency selective surface (FSS) is proposed. By loading switching diodes into FSS and making them on/off randomly, a new random-switching imaging mask is designed. By putting such random masks above a millimeter wave antenna, respective random measurement matrixes could be obtained and enough effective measurements could be achieved. By employing reconstruction algorithm, the image can be effectively reconstructed. |
