High Resolution 3D ISAR Image Formation via Interferometry Combined with Multi-Look Processing of Wide Angle Data

Abstract:
Interferometry has been successfully applied to ISAR imaging to obtain 3D images of moving targets. If wide angle ISAR data is available, Multi-Look processing can be utilized to obtain highly detailed images of targets seen from different angles. In this paper we apply interferometric processing combined with multi-look processing to ISAR turntable data observed by a multi-channel radar system. Data from two types of targets is processed, the first target is a constellation of corner reflectors at different positions and at different heights, the second target is a private vehicle.
