基于测试数据的雷达导引头技术状态评估

雷达导引头是导弹的关键部件,决定着导弹的综合作战能力。文章针对雷达导引头技术状态评估进行研究。首先,基于测试数据对雷达导引头的关键参数进行归一化处理,并引入时间修正的方法,依据装备退化规律得到装备的近期技术状态。然后,使用三角模糊数理论计算参数隶属度和可信度水平,在此基础上使用ER算法对雷达导引头特征参数的测试数据进行评估。实验使用某单位所贮存雷达导引头测试数据进行验证,表明该算法能够实现雷达导引头技术状态的实时评估,并得出评估结果的可信度。最后,基于技术状态评估结果进行雷达导引头检测规划,为合理控制雷达导引头的检测次数提供支持。

Technical Status Evaluation of Missile Radar Seekers Based on Test Data

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.
