Calibrated L-Band Terrain Measurements and Analysis Program.
Abstract
This report presents the initial results of a three year program for the collection and analysis of L-band calibrated backscatter data from various terrain types. During the first year advantages was taken of two SAR data collection programs to obtain ground measurements simultaneously with the SAR flights. These data collection flights were conducted in North Carolina during April 1984 sponsored by USGS and during August - September 1984 in Long Island, sponsored by ONR. Ground data were collected at specific sites during both SAR flights and included measurement of dielectric constant, surface roughness and moisture. The reduction of ground data and the calibration of the SAR are described. Calibration of the SAR has been verified and an error of less than 3 dB in absolute calibration of the L-band channel demonstrated. Keywords include: Electromagnetic scattering, Terrain cross section measurements, Dielectric constant, Ground truth, and Soil moisture.
