Abstract : A system is described that directly measures microwave propagation loss at low altitudes through the transmission of radio frequency signals. The system is designed to collect pathloss data over a 2 to 18 GHz band to better understand the phenomena that affect the detection of low altitude targets by radars operating in a maritime environment. Data were collected between January and April 1994 as part of the Multisensor Integration Tests held at the Naval Surface Warfare Center, Wallops Island Detachment. Detailed analysis is performed on a subset of the data; illustrations provided show the temporal and spatial character of the propagation.
