MIMO approach to implementation of radar tomography is described and preliminary results of its experimental validation using Ka-band noise waveform ground based SAR are presented. MIMO concept with time-division to of Tx/Rx channels is applied to emulate 2D aperture synthesis combined with range resolution due to wideband random signals. Two linear(More)
Conventional SAR generates 2D image using combination of range compression and 1D aperture synthesis. The range resolution of such approach is determined by the signal spectrum width, while cross-range resolution is defined by the synthetic aperture length. 2D aperture synthesis implies movement of antenna along 2D aperture and cross-range compression(More)

Current paper is devoted to coherent radiometric imaging systems. The investigated systems may be considered as a version of bistatic noise waveform radar with synthetic aperture having external reference. Reference signal in this imaging system is received from the investigated object using auxiliary receiver. Absence of need in radiation of sounding(More)
