Multi-objective Heuristic Design Approach for SAR Mission for Monitoring Local Target Area

摘要: The Korea first synthetic aperture radar (SAR) satellite with a 1-m resolution—Korea Multi-purpose Satellite-5 (KOMPSAT-5)—was successfully launched in 2013, and its successors will be continuously to monitor specific target areas. major requirements of the orbit design for KOMPSAT-5 are that mean average revisit time (ART) over Korean peninsula is no longer than 24 h repeat ground track guaranteed. For this type problem, an iterative tedious process may used derive appropriate mission satisfy requirements. During process, sophisticated coverage analysis software should employed evaluate ART local area. Moccia et al.
