针对作机动飞行的空中目标,利用目标多普勒信息和红外辐射信息,建立具有Markov跳变参数的红外系统距离估计模型,基于结构随机跳变系统最优滤波理论,提出了一种红外系统距离估计算法.基于交互式多模型算法(IMM),以红外测距为伪距量测,提出了一种新的主动雷达和红外融合算法.对一个高机动目标跟踪进行了仿真,结果表明红外距离估计误差小,融合算法跟踪精度高,性能良好,易于工程实现.
Aiming at the air target of maneuvering flight, the distance estimation model of infrared system with Markov transition parameters is established by using the target Doppler information and infrared radiation information. Based on the optimal filtering theory of structural random transition system, an infrared system distance Estimation algorithm.A new active radar and infrared fusion algorithm based on the IMM is proposed to measure the pseudorange by infrared ranging.The simulation of a high maneuvering target tracking shows that the infrared distance Small estimation error, high tracking accuracy of fusion algorithm, good performance, easy to implement.
