基于成像导引/激光测距的起爆控制算法

为解决传统侧向引信对付高速小目标存在炸点滞后问题,以成像导引头加装前视激光测距仪的制导引信一体化(Guidance Integrated Fusing,GIF)系统(简称成像GIF系统)为背景,提出基于成像导引/激光测距的起爆控制算法.该算法利用成像GIF探测系统提供的目标图像、跟踪角度、弹目距离信息,建立的基于图像处理、信息融合、数字滤波条件下的引战配合起爆控制预测算法模型,将传统的引信延迟起爆变为炸点预测起爆.仿真分析表明:该算法可有效地实现全方位、高速度和多目标类型等复杂交会条件下对目标的有效毁伤,适用于对付高速小目标.

A Burst Control Algorithm Based on Imaging Guidance and Laser Ranging

In order to solve the problem of bursting point lagging when the traditional side-detection fuze intercepted small high-speed targets,a burst control algorithm based on imaging guidance/laser ranging was put forward in this paper.A GIF(Guidance Integrated Fuze) system based on the imaging guidance,on which a laser range finder was installed,was introduced,and an arithmetic model based on imaging processing,information fusion and digital filter was set up.By using the imaging guidance picture,tracking angles and missile-to-target ranging information provided by the detecting system of imaging GIF system,the traditional fuze delay bursting was turned to prediction bursting.Simulation results showed that the algorithm could realize effective damage under high-speed and multi-targets encounter,and it’s suitable for destroying small high-speed targets.
