Health Status Evaluation of Radar Transmitter Based on Fuzzy Comprehensive Evaluation Method

Abstract

In order to improve the accuracy of health status evaluation of radar transmitter, a health status evaluation method based on fuzzy comprehensive evaluation is proposed. In this study, we first select the main influencing factors of radar transmitter, and improve the health status evaluation index set and evaluation set. This paper uses the relative degradation degree to represent the degree of deviation between the evaluation index data and the index data under normal conditions. The evaluation method uses the ridge membership function to determine the index membership and compares it with the triangular membership function. The weight determined by analytic hierarchy process (AHP) and entropy weight method is combined by combination weighting method. Then fuzzy comprehensive evaluation method is used to integrate the determined membership degree and weight to obtain the health grade membership matrix of the first level health status evaluation index. According to the principle of maximum membership degree, the health status of the first level health status evaluation index is obtained. Finally the maximum eigenvalue of the judgment matrix in the AHP is used to obtain the weight vector of each first-level health status evaluation index, and the overall evaluation result of the radar transmitter is finally determined. The calculation example analysis shows that the method can more accurately reflect the operating status of the radar transmitter, which can provide a reference for logistical support.
