Implementation method of Mosaic mode based on satellite attitude maneuver

摘要

Mosaic is a hybrid mode of spotlight and ScanSAR, which can image a large coverage at a high resolution. In this paper, an implementation method of Mosaic mode based on satellite attitude maneuver is presented. By choosing proper satellite attitude, we can obtain the radar beam pointing direction and ground footprint orientation that are required by Mosaic mode, and realize a large area seamless coverage and relatively high resolution. The required radar beam pointing direction is achieved by roll and pitch maneuver, and the required ground footprint orientation is achieved by yaw maneuver. The simulation experimental results demonstrate the availability of the proposed implementation method.
