Abstract:Radar seeker is the key component of the missile which determines the comprehensive operational capability ofthe missile. In this paper, the technical status evaluation of the radar seeker was studied. Firstly, the key parameters of ra.dar seeker were normalized based on the test data, and the time correction method was introduced to get the recent techni.cal status of equipment according to the equipment degradation rule. Then, using the triangle fuzzy number theory to calcu.late the parameter membership degree and reliability level, ER algorithm was used to evaluate the test data of characteris.tic parameters of radar seeker. Experiment used data from a coast guard missile force to verify the evaluation algorithm,showing that the algorithm could realize real-time evaluation of the missile radar seeker technology status, and the credi.bility of evaluation results could be achieved. Finally, based on the evaluation results of technical status, the evaluationplanning of missile radar seeker was carried out, which provided support for the reasonable control of the evaluation num.ber of the missile radar seeker.
