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.
