AbstractThis paper presents a narrowband channel model appropriate for modeling multipath interference in aeronautical telemetry applications. This model uses a simplified version of Bello’s aeronautical fading channel model  with the following three parameters: the specular to direct power ratio T, the direct to diffuse power ratio K and the relative Doppler shift of the specular component. Data taken from Patuxent River NAWC, Edwards AFB and White Sands Missile Range demonstrate that the model is a reasonably accurate statistical representation of the envelope (and power) fluctuations observed in the data. The model works well for those cases where a dominate line-of-sight signal component exists, as well as for those cases where the power in the specular reflections is on the order of the power in the line-of-sight component.
