Kohala Coast, Hawaii

This image shows along-track interferometry data collected over the Kohala Coast, on the northwest shore of the big island of Hawaii. The shoreline is seen in the upper right corner of the image, with the ocean appearing in the rest of the scene. The curvilinear feature is a wind-generated shear zone. These data were collected in November 1996 by the NASA/JPL airborne radar instrument, AIRSAR. This image shows the interferometric phase signature of the C-band aft and forward antennas, separated along the body of the plane. The interferometric phase is directly proportional to the component of the velocity of the scatterers along the look direction of the radar. Vertical patterns in the image are due to motion of the aircraft, the effects of which have not been completely removed during data processing.
