SAR Payload Remote Sensing Satellite Mission Analysis for Global Coverage

Abstract

The purpose of this paper is to discuss the criteria to select the orbit for satellite with SAR payload which is best suitable for the mission. The requirements of the SAR payload are spelled out, and in turn how we convert those requirements to design of orbit is discussed. The constraints of SAR payload imaging over normal electro-optical payload will be detailed. Mission requirements and payload constraints are converted into specific orbital parameters. SAR payload geometry is discussed, and off-nadir angle, repeat cycle and revisit time relation is detailed. The superiority of the selected orbit is simulated and detailed in the paper. Global coverage analysis studies are simulated and presented.
