An Optimization Method for Distributed InSAR Satellite Formation Configuration
2022 3rd China International SAR Symposium (CISS)(2022)
摘要
The formation configuration is a key factor affecting the DEM performance of distributed InSAR satellite system. By introducing the formation relative kinematic model, the constraints of interferometric baseline and interplanetary safety distance are analyzed and mathematically described, then the configuration parameters are optimized based on the heuristic optimization algorithm with the objective of coverage maximization. The simulation results show that the formation parameters obtained by the method proposed can satisfy the design constraints and guarantee the acquisition of high-precision DEM data.
