The paper describes a modelling scenario aimed at exploring high-resolution imaging, communication and in-band coexistence with other signals potential of a multi-carrier radar/communication system based on ultra-wideband waveforms obtained via orthogonal frequency division multiplexing (OFDM). Imaging performance is simulated for a well-studied scenario of stripmap SAR, for which backprojection algorithm is used in image reconstruction. The case of two airborne platforms is considered and image data communication between the platforms is modelled. This feasibility study lays foundation for subsequent analysis of a multi-platform sensor network scenario based on novel ultra-wideband radar architectures.
