美国进行照明弹现场试验的一个机构是位于尤马靶场的烟火药鑑定试验场(PER)。现场试验遇到的一个主要问题是控制和计算影响试验的环境因素。过去解决这一问题的方法要靠许多人对测试仪器进行运输、定位和操纵。所得的数据常常是不完全和不可靠的,数据质量与所花费的代价极不相称。例如在现场鑑定用飞机投放或炮射的照明弹烛光时,因带伞照明弹展开和下落时随风飘移,需要对应时间测定照明弹的位置。烟火药鑑定试验场应用3台电影经纬仪跟踪,因此需要许多人来操作。要
One agency in the United States that conducts field tests on flares is the Pyrotechnics Identification Laboratory (PER) at the Yuma Range. A major problem encountered in field trials is the control and calculation of the environmental factors that influence the test. In the past, the solution to this problem depended on many people transporting, positioning and manipulating test instruments. The resulting data is often incomplete and unreliable, and data quality is disproportionately priced. For example, in the field of aircraft lighting used to fire or shoot a candlelight, as a result of the deployment and fall of the umbrella flare, the wind needs time to measure the position of the flare. The pyrotechnics appraisal test site uses three theodolites to track, so many people need it to operate. want
