Measurement of Information Superiority of Space-based Reconnaissance System Based on OSPA

In view of the unclear mechanism of information superiority measurement and the lack of strict mathematical norms in the current information superiority, the information superiority mechanism of space-based reconnaissance system is proposed. The essence of information superiority is the degree of difference between awareness information and objective information, and the difference is calculated by OSPA set distance. The framework and mathematical model of the information superiority measurement of space-based reconnaissance system are given, which provides a new and complete process for measuring the information superiority of space-based reconnaissance system.
