Abstract_FL Aiming at the problem of target location in the process of approaching non-cooperative targets,a target location algorithm based on double-line-of-sight cooperative angle-only measurement is proposed,and the accuracy of target location can be improved by optimizing the proximity configuration.Firstly,a two-spacecraft cooperative lo-cation scheme using only line-of-sight measurement is proposed,and a target location algorithm based on extended Kalman filter is designed.Then,by introducing normal distribution crossover operator,variable mutation distribution index and simulated catastrophe,the NSGA-Ⅱalgorithm is improved and applied to the optimization of proximity configuration.Finally,the numerical simulation results show that the proposed algorithm overcomes the problems of local convergence and slow convergence of the traditional algorithms,and the accuracy of target location is improved after configuration optimization.
