Three-dimensional microwave or millimeter-wave imaging is usually performed using a fixed two-dimensional planar or cylindrical aperture that is defined using a 2D array or precise mechanical scanning of a transceiver or linear antenna array. For some applications, it is more convenient to manually pass a linear array over the scene of interest, or equivalently, move the target in front of the linear array to scan an effective aperture. This paper explores high-resolution 3D microwave imaging of a moving target by using optical motion capture to track the moving target, and developing image reconstruction techniques that account for the irregular motion.
