GeoSAR UHF Radar Observations of Vegetated Regions

Dr. Scott Hensley

Abstract

GeoSAR is a dual frequency interferometric mapping sensor designed to make elevation maps in of the true ground surface in vegetated regions. Operating at X-band and P-band from a Gulfstream II aircraft the sensor collects 80 or 160 MHz bandwidth data from the lest and right of the aircraft simultaneously. This talk will present an overview of the sensor and processing algorithms and results from two experiments conducted in coniferous and deciduous forests in California. By comparing with LIDAR and other in situ measurements the relative penetration and X-band and P-band is measured for the different canopy types.
