Side-looking three-dimensional (3D) imaging of cross-track three-aperture sparse array synthetic aperture radar (SAR) based on compressive sensing (CS) is investigated in this paper. Conventional SAR has accomplished high resolution imaging on two-dimensional (2D) azimuth-range plane. Using the array structure in cross-track direction, the height resolution can be obtained and 3D imaging is achieved...
Time-frequency transform is applied into InISAR for multiple moving targets imaging. By means of interferometric processing to range-Doppler images, the range-azimuth image can be derived from the interferometric phase. The restriction of millimeter-wave (MMW) phase wrapping is solved by multiple baseline.
