An Advanced VHF/UHF Short Range, Groundwave Propagation Model for Paths With Near-Earth Antennas

Abstract

Short range VHF and UHF paths between devices with antennas very close to, or on the earth such as: Unattended Ground Sensors (UGS) and Intelligent Munitions Systems (IMS), are attenuated above free space values by the lossy earth itself and any obstructions between a transmitter and receiver pair. Due to a paucity of measured data and propagation methods for the cases of military interest, an innovative propagation model is described that combines the seminal work of Franceschetti et al and Norton.
