MITRE has made measurements of the wide bandwidth (1‐MHz bandwidth) impulse response of HF propagation modes for midlatitude paths in the United States. These paths included near‐vertical incidence, 2000 and 3000 km lengths, and primarily supported one‐hop F layer propagation. On the basis of these measurements, this paper proposes a stochastic representation for the path loss fluctuation of propagation modes observed for 15‐min time intervals. When expressed in decibels, this path loss is modeled as a normally distributed autoregressive process of low order. Estimates of the parameters for this model are extracted from the data for a variety of transmission conditions. A model order of 1 is suggested for link modeling.
