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。
Using the infrared fuze of imaging seeker information, a series of dynamic infrared images can be obtained from the complete to the part, which can realize the foresight detection. Aircraft attitude recognition for imaging fuze to determine the aiming point is of great significance. The motion characteristics of aircraft target at high-speed rendezvous are analyzed. Genetic algorithm is used to determine the rotation and head position of the target image on the image plane, as well as the distance information provided by the distance measuring device, the length of the target image and the system parameters of the infrared detector The pitch of the target situation, and finally use the target axis azimuth and the invariance of the high and low angles during the cross-body engagement to achieve the recognition of the flight attitude of the aircraft.
