双频段复合制导是改善复杂电磁环境下雷达导引头检测性能及抗干扰能力的一条重要途径.针对双频段复合雷达导引头,本文提出了一种适用于双频段雷达的目标融合检测及跟踪算法.该算法利用双频段信息自适应构建权重因子,基于决策层的投票融合策略完成对目标的检测及参数估计.仿真实验结果表明,该算法有效提高了导引头目标检测能力及跟踪精度,改善了干扰条件下的导引头检测性能.%Dual-frequency band compound guidance is an important method for radar missile seeker to improve the performance of target detection and anti-jamming. A novel method for target detection and tracking based on multi-sources information fusion is proposed for dual-band radar seeker. The weight fac-tor is built adaptively with dual-frequency information, then the vote strategy is used for target detection and parameters estimation. The simulation results show that the proposed method can improve the detec-tion probability and tracking accuracy,especially under a jamming case.
