Simulation Analysis of Multi-satellite Joint Detection Activity Target Capability

Abstract

Under the condition of informatization, multi-star situational awareness of active targets in the mission area can greatly determine the trend of the whole mission. In order to measure the capability of multi-satellite joint detection active target, this paper introduces the concept of perception degree, deeply analyzes the probability of optical satellite detection, and USES the call search method to determine the calculation model of effective time of satellite detection. Aiming at the specific task area, the grid space is introduced and the simulation evaluation process is given. Finally, taking a certain region of China's territorial sea as the detection object, taking the existing five optical satellites as the basis, and using STK software for simulation analysis, the results show that the established perception model can better reflect the joint detection effect of multiple satellites.
