再入段测量手段很多,可借助于光测设备或电子测量设备,二者之间各有所长,互为补充。尤其光测设备具有特殊的优越性,它能取得图象,形象地记录空中目标的姿态、级间分离、遭遇情况等飞行事件;测量精度高,并能测量飞行目标在弹道各段的辐射特性参数;抗干扰能力强,不受地面杂波和再入黑障的影响;稳定可靠,设备简单等;使电子测量设备望尘莫及,是再入段测量中必不可少的有效工具。美国靶场无论从规模大小还是技术先进性方面,都具有相当的代表性。现就美国两个主要再入靶场的光测设备作一介绍。
Re-entry into the paragraph means a lot, by means of optical measuring equipment or electronic measuring equipment, between the two have their own strengths, complement each other. In particular, optical measurement equipment has special advantages, which can capture images, vividly record the attitude of aerial targets, interstage separation, encounters and other flight events; high measurement accuracy, and can measure the flight target radiation characteristics of the various segments of the ballistic Parameters; strong anti-interference ability, not affected by ground clutter and re-entry blackout; stable and reliable, simple equipment, etc .; electronic measurement equipment far behind, is an essential tool for reentry segment measurement. The U.S. shooting range is quite representative in terms of its size and technological advancement. Now on the United States two major re-entry range of photometric equipment to make an introduction.
