Inhalt:
The resulting image of a SAR or ISAR processing of a moving ship is highly impacted by its dynamics. TSA (Thales Systemes aeroportes) has studied for DGA (French Ministry of Defence) a new algorithm for airborne radar. Performances have firstly been evaluated using real raw data acquisitions of several scenes. But, in order to extend the available measurement campaigns and to increase the number of test cases, simulated radar signals have been used. The simulation uses for each ship a 3D EM model produced by MOCEM V3 software. A dedicated raw data simulator has been developed by ALYOTECH and is currently optimized in the version V4 of the MOCEM software.
