基于仿真数据的相控阵天线毁伤小子样试验鉴定方法

Few Sampling Phased Array Antenna Damage Test Identification Method Based on Simulation Data

针对反辐射战斗部预制破片对相控阵天线目标毁伤试验鉴定方面存在的困难,围绕小样本条件下合理利用仿真数据实现破片毁伤效能试验鉴定展开方法的研究.先利用试验室条件获取少量试验数据,再根据试验条件利用数值仿真方法获取大量的试验数据.通过试验数据和仿真数据的融合,采用基于相容性概率的可信度近似求法判断数据的可信度.最后在Bayes小子样统计推断基本原理的基础上,采用融入可信度后的Bayes估计方法对试验数据做出较为精确的评估.

This thesis considers anti-radiation warhead prefabricated fragments damaging of phased array antenna. In the condition of few sampling, simulation data is used to do damage identification test of prefabricated fragments. Firstly, few test data is obtained in the laboratory condition. Secondly, a lot of test data is obtained based on numerical simulation methods. By combining experimental and simulated data, the reliability of other data can be judged according to the compatibility probability. Finally, according to the bayes few sampling statistics inferential theory, more precise evaluation of the test data is carried out by bayes estimation methods with reliability.
