摘要

本文利用有源毫米波合成孔径雷达(SAR)成像系统实现了不同距离隐蔽物的高分辨率全息成像。为了实现目标场景上的合成孔径，该系统由一个二维全可控平移平台组成，该平台可以分别在水平和垂直方向上进行扫描。针对隐身目标的全息重建，采用了带宽为4GHz的调频连续波(FMCW)雷达，同时研究了基于该系统的波数域三维全息成像算法。实验结果验证了系统和算法的有效性。

Millimeter-Wave SAR for Concealed Item Holographic Imaging

In this paper, an active millimeter-wave (mmWave) synthetic aperture radar (SAR) imaging system is utilized to achieve high-resolution holographic image of concealed objects at different distances. To realize a synthetic aperture over the target scene, the system consists of a two-dimensional fully controllable translational platform which can scan in horizontal and vertical directions respectively. For holography reconstruction of concealed objects, the frequency-modulated continuous-wave (FMCW) radar with 4GHz bandwidth is employed, meanwhile, the wavenumber-domain 3-D holographic imaging algorithm based on the system is investigated. The experimental results confirm that our system and algorithm are valid.
