  • ELECTROMAGNETIC NON-LINE-OF-SIGHT IMAGING METHOD BASED ON TIME REVERSAL AND COMPRESSED SENSING
    Publication number: 20230065110
    Abstract: An electromagnetic non-line-of-sight imaging method based on time reversal and compressed sensing is provided. The electromagnetic signal passively scattered by the target behind the obstacle is received by the antenna, the contour imaging of the target is realized by using compressed sensing, the signal-to-noise ratio of the electromagnetic signal of the target is improved by using time reversal for the contour area, so as to achieve the purpose of staring at and detecting the non-line-of-sight target; a random radiation signal is transmitted for multiple times through active metasurface modulation, compressed sensing is performed for calculation imaging after receiving the signal to judge the number of targets and the contour area in the occluded area; for the target contour area, the amplitude and phase of signals obtained at different positions are adjusted by the active metasurface, so as to focus and scan the electromagnetic signals at different positions behind the obstacle.
