摘要

低层大气传播超宽带(LATPROP-UWB)系统部署在耦合海气过程和电磁导管研究(CASPER)东部战役中,用于测量2-40 GHz的距离相关传播损耗。利用耦合海洋/大气中尺度预报系统(COAMPS)获得CASPER East期间的折射率预报。利用距离相关的预测折射率剖面和抛物波方程代码来模拟传播损耗。比较了模拟和实测的传输损耗,计算了COAMPS的预测精度。

COAMPS Refractivity Forecast Evaluation Using LATPROP- UWB Propagation Loss Data
Lower Atmospheric Propagation Ultra Wide Band (LATPROP-UWB) system is deployed during Coupled Air-Sea Processes and Electromagnetic Ducting Research (CASPER) East campaign to measure range-dependent propagation loss for 2–40 GHz. Couple Ocean/Atmosphere Mesoscale Prediction System (COAMPS) is used to obtain refractivity forecasts during CASPER East. Range-dependent forecast refractivity profiles are used with a parabolic wave equation code to get simulated propagation loss. The simulated and measured propagation loss are compared to compute COAMPS forecasting accuracy.
