Path-Loss Measurements in a Forested Environment at VHF

Abstract

Designing a radar system capable of detecting objects concealed by foliage requires path-loss data and the development of path-loss prediction models. The challenge is to design a system with antenna elements of manageable size, while keeping foliage signal attenuation as small as possible. We took a series of measurements to characterize path loss in a mostly deciduous forest. Results show that the parameter values that give the least attenuation because of the intervening woods are the lowest frequencies and transmit horizontal, receive horizontal polarization (HH).
