Distributed Spaceborne Tomosar Formation Configuration Optimization Method Based On NSGA-II

Résumé fourni par la source

This paper presents a distributed spaceborne To-moSAR formation configuration optimization method based on NSGA-II. The method mainly consists of three parts: distributed spaceborne TomoSAR model, formation configuration optimization model, and NSGA-II optimization process. It can optimize formation configuration of distributed spaceborne TomoSAR system during a revisit cycle for different satellites and different radar parameters. The correctness and effectiveness of this method are verified by simulation experiments using PIESAT-1-A-01’s satellite and radar parameters. The experimental results not only prove the correctness of the formation configuration optimization method, but also show the great potential of the method in meeting the needs of tasks such as urban 3D mapping and forest monitoring.
