The aim of this study is to support the modelling of the radar function when simulating systems at higher levels. Especially it deals with monostatic synthetic aperture radar for "Ground Moving Target Indication" (GMTI). The study comprises a short introduction to airborne MTI and especially SAR with DPCA (Displaced Phase Centre Antennas) and further there are some estimations regarding the maximum coherency time when limited by linear and rotational movements of a target. Also there are some aspects on application modes and approximate expressions for some performance parameters limited by the measurement geometry. The financial source has mainly been the project NFFP-427 (E7779) from the Swedish Defence Materiel Administration.
