摘　　要：针对复杂环境下的毫米波/红外复合制导,提出一种基于决策信息的改进加权融合算法.通过分析导弹运行状态和受干扰情况,获得制导的决策信息.对经无迹卡尔曼滤波(UKF)估计分别得到的毫米波/红外量测信息进行改进的自适应加权融合,得到融合后的制导信息.仿真实验表明,所提方法融合精度高,能有效提高复合制导的性能.According to millimeter wave and infrared compound guidance under the complex background, an improvement weighting fusion algorithm based on decision information is proposed. The decision information of guidance is obtained by analyzing missile running status and the disturbed condition. The measured information of millimeter wove and infrared is acquired by unscented Kalman filter（UKF） estimation respectively. With an improvement self-adapting weighting fusion algorithm, fused guidance information is obtained. The simulation result shows that the precision of this method is high, and the performance of combined guidance can be improved effectively.
