International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / Data collected during July 1999 at Edwards EAFB by the Advanced Range Telemetry (ARTM) program
is examined to characterize the dynamic behavior of multipath interference in an aeronautical telemetry
channel. Multipath fade events are analyzed in the frequency domain to show how these fades appear,
evolve, and disappear from the channel. A channel model and examples from the channel sounding data
are used to show the dynamic nature of these fade events. The Doppler power spectrum is used to
quantify the exact time-varying nature of the multipath fade events. The coherence time, or the amount
of time the channel can be viewed as unchanging, is obtained from the Doppler power spectrum and is
calculated to be 100 ms in the data sets examined in this paper. This implies that adaptive multipath
mitigation techniques must have an adaptation bandwidth of 10 Hz.
