摘　　要：针对光敏管阵列激光靶体积估算现存的参数多、过程繁琐等问题,提出了光敏管阵列激光靶基于横截面积分的体积估算方法。该方法通过计算每个采样时刻物体遮挡X、Y轴的尺寸得到物体在该时刻的横截面积,再以物体在相邻采样时刻内运动的间隔位移为积分元对所有采样时刻物体的横截面积进行积分完成对物体的体积估算。仿真表明基于横截面积分的体积估算算法具有误差小、可靠性高的优点,在提高靶场测试的测试范围和测试精度方面,具有很大的实用价值。In the view of the problems that there were too many parameters and cumbersome processes in esti-mating volume of obj ects for photodiode array laser target,a volume-estimating method based on cross-section integration for photodiode array laser target was proposed.The method estimated obj ect＇s dimension that ob-structed the X and Y axis to obtain the obj ect＇s cross-sectional area at every sampling,and then conducted inte-gration for all the cross-sectional area to complete volume estimation of the obj ect with interval displacement be-tween adj acent sampling time as the integration element.Simulation result showed that the volume estimation al-gorithm based on cross-sectional area integration had small error and high reliability.
