The launch of the Canadian Space Agency{close_quote}s RADARSAT will provide the capability to supply imagery acquired from different instrument look angles, resulting in a multi-incidence view of an area of interest. Previous research has utilized multi-incidence imaging to map land use/land cover and to model soil moisture content. This research utilizes an innovative approach to the use of multi-angle SAR imagery to detect differences in land use/land cover. In this study, plant canopies and bare soil are imaged with multi-angle and multi-frequency data acquired with the airborne NASA/JPL AIRSAR instrument. Findings are relevant for possible applications of data from the soon to be orbited RADARSAT instrument. Backscatter from a distributed target, such as vegetation, is the product of microwave absorption and scattering interactions with all features within the imaged area. The intensity of the backscatter from the area varies with the angle of the incident wave. This investigation uses this physical understanding of multi-angle imaging to describe the differences in scattering from different crop covers. Using the fully polarized, three frequency, C-, L- and P-Bands, airborne NASA/JPL AIRSAR instrument, land use/land cover of an area in central Pennsylvania was imaged at look angles of 30{degree} and 45{degree}. C-Band, hh polarized data will be examined in this study as it is the same configuration as the RADARSAT instrument. Land use/land covers in the study include bare fields, alfalfa, corn, and trees. {copyright} {ital 1996 American Institute of Physics.}
