Abstract:
The aim of this work is to simulate a flow of ISAR images for a ship at sea seen from an airborne radar, in rigorously the same configuration as it has been measured by a real SAR using the recorded motion data of both radar, ship and ship attitudes. We use MOCEM and DUEL simulation softwares to produce range Doppler profiles from CAD models and radar observation characteristics. Comparison examples are given with real data acquired by FFI with the PicoSAR(R) X-band COTS radar from Leonardo company.
