UAVSAR collected its first image data on September 18, 2007 in a flight over the Rosamond
Lake Bed in California (on a heading of 350 deg and at an altitude of 9150 m), where there is an array
of trihedral corner reflectors used for calibration. The radar was operated in its polarimetric mode and
transmitted an 80 MHz bandwidth signal giving a range resolution of 1.66 m. The image covers an area 11 km wide by 57 km long. Data was received in
the 12 to 8 bit Block Floating Point Quantization (BFPQ) compression mode. Shown is the HH polarization
image. The beginning of the
image is over Palmdale, CA. A small segment of the California Aqueduct can be seen in the top left
portion of the image with the Palmdale Airport visible just below. Also visible further down in the
image is the Rosamond Lake bed and the array of NASA corner reflectors (as well as the reflectors
for other systems) which appear as bright point like features against the radar dark background of the
dry lake bed. They are each separated by about 600m. The image ends just south of the town Mojave, Ca. This image is in radar slant plane coordinates
and thus will appear somewhat distorted relative to standard optical imagery or maps.
