Model of the Radio Images of Objects in Holographic In-Plane Surveillance Radar Systems Based on an Analytical Approximation Method

A simple analytical approximation for computing radio images of 3D objects is proposed for an airborne MIMO-type holographic in-plane surveillance radar systems (PSRSs). The model is intended for realtime estimation of the quality of 3D images in such PSRSs during selection of the main parameters of the MIMO antenna system, the frequency band, and the bandwidth of the sounding signal. The results can also be applied to conventional PSRSs, a factor that makes it possible to perform a comparative analysis of PSRS versions and select the PSRS embodiment.
