红外探测技术对多目标弹道参数的测量

在对多目标探测所用传感器的选择、目标提取和数据处理等三方面技术问题进行分析论证的基础上,提出了一种新的多、弱、小、暗目标近地弹道参数测量方法。采用红外热像仪合理布站,对运动的多个目标进行空间定位;采集多目标近地区域的下落图像,拟合出相应的轨迹,然后根据多条轨迹得到诸如目标空间坐标、轨迹、速度等弹道参数。这种方法可用于测量靶场落点和近地轨迹等;尤其是在对子母弹子弹群的近地弹道参数及落点的测量中,通过后期处理,可快速精确地报出各子弹的落点坐标。

Measurement of ballistic parameters for multi-target with IR detection techniques

A new method for measuring near-earth orbit ballistic parameters of multi, faint, small and dim targets is proposed on the basis of analysis and demonstration of sensor selection for multi-target detection, target extraction and data processing. The spatial positioning for moving multi-target is carried out by reasonably distributed multiple infrared thermographs. Through sampling the falling images of multi-target in near-earth space, corresponding multi-trajectory is fitted. The ballistic parameters such as spatial coordinates, trajectories and rates of targets can be obtained based on the multi-trajectory. This method can be applied to measurement of impact point in range, near-earth orbit. Particularly for the measurement of near-earth ballistic parameters and impact points of shrapnel, it can accurately report the impact point coordinates of various bombs through post-processing.
