地空反辐射导弹红外/被动微波复合导引头数据融合技术研究

数据融合技术是多模复合导引头的核心问题和关键技术。针对被动微波／红外复合导引头，通过分析武器系统对融合处理系统的要求，设计了数据融合处理的总体方案；提出了基于预测一观测差和预测一预测差的单导引头干扰判断和多导引头干扰判断方法；最后针对导弹攻击过程中的不同阶段设计了数据融合策略。结合实测数据的实验，验证了干扰判断和融合策略的有效性。

Data Fusion Technique of IR/Passive Radar Multi-mode Guidance Seeker for Surface-to-air Anti-radiation Missile

Data fusion is one of the key problems and techniques for multi-pattern composite guidance seeker. On the ground of analyzing requirement of weapon system to data fusion system of the in?frared/ passive radar composite guidance seeker, the general flow of data fusion was designed; interfer?ence judgement methods of the single and multiple sensors were proposed based on differences between prediction and observation, prediction and prediction; the data fusion strategy was designed at differ?ent phases in attacking process of the missile. Effectivenesses of interference judgement and fusion strategy were verified by measured data in a real experiment.
