1. A method of operating an ultra-wideband radar imaging system comprising processor operatively coupled to an antenna with at least one receiver and a plurality of transmitters operating in multi-static mode, the method comprising:
receiving by said at least one receiver a plurality of signals, each respectively representing return data in a channel associated with the receiver and one of the transmitters among said plurality of transmitters, thus giving rise to a plurality of spatial data channels; among said plurality of spatial data channels selecting, by the processor, data channels for further processing; and providing, by the processor, volume visualization by processing data corresponding merely to the selected spatial data channels, wherein selecting, by the processor, spatial data channels for further processing comprises: generating a two-dimensional map of a plurality of representative channels corresponding to said plurality of spatial data channels; dividing the generated two-dimensional map into a plurality of collection areas, each matching a contribution criterion, wherein the contribution criterion requires substantially equal contribution of all representative channels mapped to a given collection area; collecting from each collection area N Nmax representative channels, where Nmax is a threshold indicative of a maximal number of channels to be collected from a collection area; and selecting spatial data channels corresponding to the collected representative channels. |
