Narrowband channel model for aeronautical telemetry

A narrowband channel model for multipath fading in aeronautical telemetry applications is described. This channel is composed of a line-of-sight signal, a specular reflection whose strength is 20% to 80% that of the line-of-sight signal, and a diffuse multipath component whose power is 10 to 20 dB less than that of the line-of-sight signal. Thus the channel is close to additive white Gaussian noise with strong specular interference. Data collected from three test ranges is used to test the accuracy of the model and form the basis of the description.
