【摘要】 本文根据人工影响天气(以下简称人影)作业安全射界管理需求,讨论分析了影响人影作业安全射界因素包括装备性能、弹药稳定性、高空气流、站点海拔和人员操作水平等,提出一种人影作业安全射界精细化绘制思路和方法,设计开发了基于高分辨率卫星影像数据和数字高程模型数据(以下简称DEM数据)人工标识技术的人影安全射界绘制系统。经实践应用,该系统输出的人影作业安全射界图,可解决传统射界图安全标记要素不全、绘制分辨率不高、信息化程度低等问题,对提升作业效益和安全管理水平具有一定的实用价值,可以向开展人影作业的各级单位推广使用。更多还原

【Abstract】 According to the safe firing range management requirements of weather modification operation,an analysis is made of the factors influencing the safe firing range of weather modification operation,including equipment performance,ammunition stability,high altitude airflow,site elevation and personnel operation level,etc.This paper puts forward a method for drawing the safe firing range map of weather modification operation,and the specific steps are as follows:(1)the information interpolation processing of the ejection data tables;(2)the artificial identification of the sensitive area of the ground safe operation;(3)the inverse calculation of projectile impact points corresponding to initial firing data;(4)the error correction design of different influence factors;(5)the fusion processing of geographic information data;(6)the output of the safety shooting range map.This paper also designs the system for drawing safety shooting range maps based on the artificial identification technology of high-resolution satellite image data and digital elevation model data(DEM data).Practical application shows that the safe firing range map outputted by the system can solve the problems of incomplete safety-marking elements,low resolution,and low level in information in the traditional maps,has practical value for improving the operational efficiency and safety management level,and can be popularized to all levels of weather modification operations.更多还原
