【摘要】 利用成像导引头信息的红外引信可以获得目标由完整到局部的一系列动态红外图像,实现前视探测。飞机姿态识别对成像引信确定瞄准点具有非常重要的意义。分析了高速交会情况下飞机目标的运动特性,利用遗传算法确定像平面上目标图像的旋转情况和机头位置,以及测距装置提供的距离信息、目标图像的长度及红外探测器的系统参数确定目标的俯仰情况,最后利用弹目交会过程中目标轴线方位角和高低角的不变性实现了飞机飞行姿态的识别。更多还原

【Abstract】 The system of infrared imaging fuze based on imaging seeker information can get a series of dynamic infrared images of target from the whole to a part and realize forward looking detection. The recognition of aircraft status is of great significance to fix aimpoint by imaging fuze. The moving characteristics of aircraft in high speed encounter is analyzed and the rotating status of target image on image plane and the position of aircraft nose are obtained through genetic algorithm. The pitching status of aircraft is obtained by utilizing the distance information provided by measurement device, the length of target image and the system parameter of infrared detector. Finally, the recognition of aircraft status is realized by use of the invariability of azimuth angle and pitch angle of target axis during encounter of missile and target. \;更多还原
