Threat Level Assessment by Imaging Reconnaissance Satellite to Ground Target Based on Fuzzy Evaluation

In modern warfare, the reconnaissance satellite finds the target and makes the target have the risk of being attacked, in order to estimate the threat degree of imaging reconnaissance satellite to ground target detection during the transit period, this paper proposes a threat level evaluation method of reconnaissance satellite to ground target based on fuzzy evaluation, which comprehensively considers the discovery, recognition, confirmation and discrimination of imaging reconnaissance satellite to target, constructs the threat level fuzzy membership function corresponding to different detection probabilities, uses the fuzzy evaluation criteria and establish the target threat level evaluation model. A set of calculation results of detection probability are given, and the unique threat level is determined. The results show that the algorithm is effective and feasible and it can provide a reference for the effectiveness evaluation of reconnaissance satellite.
