A Real-Time Correlation Method for Space Objects in Satellite-Based Coordinate System

A real-time correlation method for space objects using radar observations is proposed in this paper. According to the orbit prediction error characteristics of space objects, an error model is established in the satellite-based coordinate system, and the correlation threshold is calculated based on the Hill equation and the inner accuracy of orbital elements. In order to meet the requirements of engineering application, the double decision is used to improve the efficiency. The simulation results verify the feasibility and effectiveness of the method.
