Abstract

As part of the HAVE LACE (Laser Airborne Communications Experiment) program, optical scintillation data was collected and is being analyzed. This data will be used to examine the effects of scintillation on air-to-air laser communication performance. The HAVE LACE terminals use direct detection of a pulsed diode laser. The random variations in received signal strength, called scintillation, are caused by the time varying index of refraction, called atmospheric turbulence. The scintillation data that was collected is compared to terrestrial scintillation data in an effort to validate atmospheric turbulence models. Valid models can then be used to aid in the design of air-to-air laser communication terminals that provide acceptable probability of error performance.

机载激光通信闪烁测量
作为激光机载通信实验(HAVE LACE)计划的一部分,收集了光学闪烁数据并正在进行分析。这些数据将用于研究闪烁对空对空激光通信性能的影响。LACE终端使用脉冲二极管激光的直接检测。接收信号强度的随机变化,称为闪烁,是由随时间变化的折射率引起的,称为大气湍流。将收集到的闪烁数据与地面闪烁数据进行比较,以验证大气湍流模型。有效的模型可以用来帮助设计提供可接受的误差概率性能的空对空激光通信终端。
