Three-dimensional microwave imaging with adaptive single-input-multiple-output SAR

Three-dimensional single-input-multiple-output synthetic aperture radar (SIMO-SAR) imaging method is proposed in this paper based on Capon adaptive beam-forming technology, and we have designed the downward-looking geometry architecture and signal echo model of the imaging system. Imaging algorithm is derived from the model and simulated. The advantages of three-dimensional imaging with SIMO-SAR are shown by the simulation results that it can get the height information of the targets besides the azimuth and range information, thus the targets can be located accurately and viewed in a stereogram. Furthermore, the algorithm can give better three-dimensional resolution.
