DARPA的光学射频通信辅助设备（ORCA）计划旨在通过机载平台为作战人员带来高数据速率网络。最近，诺斯罗普·格鲁曼公司（NGC）在内华达州托诺帕附近的内利斯空军靶场的内华达州试验和训练靶场（NTTR）对ORCA系统进行了测试。中佛罗里达大学（UCF）进行了一项平行试验，测量折射率结构参数的路径平均值，湍流的内部尺度，以及沿沿着ORCA从机载平台到羚羊峰地面的传播路径的湍流的外部尺度。此外，天文台亦在羚羊峰地面设置气象仪器，量度山顶的天气情况。本文介绍了预期的大气条件的通道，模型所使用的UCF的测量，路径平均值的三个大气参数，和一个Cn 2剖面模型作为高度的函数的背景信息。
The DARPA Optical RF Communications Adjunct (ORCA) program was created to bring high data rate networking to the warfighter via airborne platforms. Recent testing of the ORCA system was conducted by the Northrop Grumman Corporation (NGC) at the Nevada Test and Training Range (NTTR) at the Nellis Air Force Range near Tonopah, NV. The University of Central Florida (UCF) conducted a parallel test to measure path-averaged values of the refractiveindex structure parameter, the inner scale of turbulence, and the outer scale of turbulence along the ORCA propagation path from an airborne platform to the ground at Antelope Peak. In addition, weather instrumentation was set up at ground level on Antelope Peak to measure local conditions on the mountain top. This paper presents background information on expected atmospheric conditions for the channel, models that were used by UCF for the measurements, path-averaged values of the three atmospheric parameters, and a Cn2 profile model as a function of altitude.
