Abstract:

High earth orbit missile warning satellite constellation is composed of several satellites operating on the geostationary orbit and highly elliptical orbit. The coverage requirement and positioning precision are the most important objectives of its constellation optimization. For the coverage optimization, the coverage requirement is determined by the threat degrees of different areas. For the positioning optimization, the positional precision in multi coverage and single coverage regions is different. These two facts define the constellation optimization as a complicated multi-regional multi-objective problem. To deal with this problem, a multi-layer multi-objective model which is able to describe the problem efficiently is proposed. Then a method which defines the optimization as a process with two steps is introduced to solve the problem. In the process of coverage optimization, a rapid method based on search space transformation is introduced to the calculation of Pareto optimal, which is time saving and improves the accuracy. In the process of positioning optimization, the ordinal optimization is proposed to save the time of optimization. Finally, the validity of the algorithm is tested by the numerical experiment. And the time consumption of the entire optimization is less than one minute.
