Abstract
Aiming at the need of health evaluation of spaceborne modulation and demodulation equipment, a method of load health evaluation based on order relation analysis and entropy weight method was proposed, and membership function was introduced to solve the matching problem of equipment weight and health level. Firstly, the health index system of spaceborne modulation and demodulation equipment is established, and then the indicators are uniformly processed. The subjective weights of each index are determined by the method of order relation analysis and expert experience. By adding entropy weight method to the data features, the objective weight of each index is obtained, and the comprehensive weight is obtained by Lagrange multiplier method. Then the health membership function is obtained based on fuzzy set theory to make the comprehensive weight of each index match the health status evaluation results. Finally, the feasibility of the index system and evaluation method is verified by simulation experiments.
