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

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

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—观测差和预测—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 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 infrared/passive radar composite guidance seeker, the general flow of data fusion was designed; interference 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 different phases in attacking process of the missile. Effectivenesses of interference judgement and fusion strategy were verified by measured data in a real experiment.
