An optimal algorithm for radiometric imaging with high spatial resolution is obtained. An analytical expression for the ambiguity function (AF) of narrow-band, multi-band and ultra-wideband (UWB) radiometric complexes with multi-antenna systems is derived. The impact of the antennas geometry, antennas number, as well as the narrow-band, multi-band and UWB predetection section on spatial resolution is investigated. It is shown that using multi-antenna systems with multi-band and UWB signal processing contributes to the formation of AF with one main lobe.
