A comprehensive evaluation method combining grey system theory and order relation analysis (G1) is proposed to solve the problems of various and uncertain factors affecting the supportability of radar equipment. Firstly, according to the requirement of radar equipment supportability, the evaluation index system of radar equipment supportability is constructed. Secondly, order relation analysis (G1) is used to determine the weight coefficient of each evaluation index. Finally, the grey scale and whitening weight function are determined by expert scoring value and grading standard, and the guarantee grade of radar equipment is obtained by using grey evaluation model. The accuracy of this method is verified by an example, which provides a new idea for the supportability evaluation of radar equipment.

Aiming at the difficult problem of radar equipment evaluation caused by complex structure and many influencing factors, a comprehensive evaluation method of radar is proposed. This paper starts with the concept, elements and steps of comprehensive evaluation, and introduces the process of comprehensive evaluation in detail. The types of index weighting methods and the historical process of evaluation methods at home and abroad are summarized. According to the practical working experience, the radar comprehensive evaluation index system is constructed, and combining the characteristics of subjective and objective weighting methods, the combined subjective and objective weighting model is designed. On the basis of analysing the results of various evaluation methods, a combination model of evaluation results is constructed. The radar equipment is evaluated according to the scoring data of experts on the supportability of radar equipment. The effectiveness of the method is verified by an example.
