Performance indexes analysis for multi-observation platform system

Because of the more and more complex requirements of tracking environment, single-observation platform is difficult to deal with the challenges of the future war. Compare with it, the multi-observation platform can overcome the uncertainty and limitation through coordination and complementarity between the platforms. How to optimize the allocation of the limited sensor resources is a key problem in the platform management system. The existing evaluation indexes of multi-observation platform are based on its operating parameters and are designed under the precondition of given network topology. There is less research on the optimal allocation of multi-observation platform. In this paper we put forward three kinds including four evaluation indexes, for example the time-spatial coverage(time coverage and spatial coverage), the observation completeness and the platform security. The performance evaluation of the platform is obtained, by defining and relationship analysis of platform parameters. We try to provide some thoughts and ideas for the performance evaluation, construction and optimization of the multi-platform observation system.
