Abstract

In this paper, the basic performance of MTI/SAR radar in ship and ground vehicle applications is analysed. If a single antenna beam scans a sector, significant degradations in MTI sensitivity and SAR resolution occur due to the reduced dwell time on target. Improved performance can be achieved by digital array beamforming with multiple beams, or high speed scanning. SAR needs accurate phase error compensation by inertial measurements or autofocus due to the non-linear movement path of the antenna.
