Abstract
SAR tomography based upon MIMO concept with channels time-division is described and some results of its experimental validation using Ka-band ground based noise waveform SAR are presented. Two different linear synthetic apertures have been used for both transmit and receive antennas oriented in vertical and horizontal directions, respectively. Range resolution in SAR tomography is determined by power spectrum width of the transmitted signal, while its cross-range resolution is defined by 2D aperture dimensions and working wavelength. The approach suggested is applicable for generation of 2D and 3D coherent SAR images and radio-films provided data acquisition and signal processing in real time.
