Abstract

We describe MIMO approach to implementation of radar tomography and present preliminary results of its experimental validation using Ka-band noise waveform ground based SAR. The range resolution in radar tomography is determined by power spectrum width of the transmitted signal, while cross-range resolutions are defined by 2D aperture dimensions. We apply MIMO concept with time-division to emulate 2D aperture synthesis combined with range resolution due to wideband random signals which enables generation of 3D coherent radar images. Two linear synthetic apertures have been used for transmit and receive antennas oriented in vertical and horizontal directions, respectively.
