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.
Aiming at the millimeter-wave / infrared composite guidance in complex environment, an improved weighted fusion algorithm based on decision-making information is proposed. The guidance decision information is obtained by analyzing the operational status of the missile and the disturbed situation. For unscented Kalman filter (UKF) The obtained MMW / IR measurement information is estimated to improve the adaptive weighted fusion, and the fused guidance information is obtained.The simulation results show that the proposed method has high fusion accuracy and can effectively improve the performance of the composite guidance.
