ALP FOPEN Site Description and Ground Truth Summary
Abstract
During the fall of 1988, an extensive set of multifrequency (1.25, 5. 3 and 9.35 GHz), and in some cases polarimetric airborne SAR imagery was collected over Camp Ripley, Minnesota, by the ERIM/NADC P-3 SAR System. This data collection was sponsored by the AFWAL and the MIT's Lincoln Laboratory (MIT/LL). The acronym for this data collection was ALP, which stands for AFWAL/ LL/P-3. This report deals with test sites established to more clearly understand the phenomenology associated with radar detection of targets obscured by vegetation. The test sites consisted of trihedral corner reflectors deployed in six different tree stands. Ground truth collected during this activity includes: (1) ground photography of each site; (2) climatic data for the experiment period; (3) measurement of tree density, diameter, height and placement relative to the target for each site; (4) for some cases, measurement of branch and needle biomass, diameter, angles and length; (5) allometric equations describing the distribution of above ground biomass for the various tree species; and (6) dielectric measurements of the major tree species found within the test area. Keywords: Aspens; Jack pines; Radar ground targets; Foliage penetration experiment; Tree characteristics; Dielectric measurements.
