Lunar InSAR satellite formation configuration design based on multi-objective ant-lion optimization algorithm
The problem of lunar interferometric synthetic aperture radar(InSAR)satellite formation configuration design is studied.Firstly,the relative dynamic model of lunar InSAR satellite based on relative eccentricity/inclination(E/I)vector is established.Then,the long-term stable flight conditions of formation flying under the perturbation environment of lunar orbit are studied.Taking the relative altimetry accuracy and fuzzy altitude as optimization indexes,and considering the inter-satellite safety,the objective function of formation configuration design is given.In response to the existing research methods are unable to solve the multi-objective problem of configuration design,an improved multi-objective ant-lion optimization algorithm is applied to achieve the configuration design of lunar InSAR satellite formations.Simulation results show that the proposed algorithm is better in baseline utilization rate,which verifies the adaptability and effectiveness of the proposed algorithm.
