Abstract :
Predicted and measured values of radar backscatter and of internal wave surface currents are compared using data obtained during the SCATTMOD internal wave experiment. Radar backscatter and surface truth measurements were obtained during six days in August 1985 and cover nine sets of tide-generated internal waves in the Georgia Strait, Canada. The radar portion of this data consists of approximately 75 sets each of C- and Ku-band fanbeam airborne scatterometer signals, each processed to 25 incidence angles and an along-track resolution of either 12.5 or 6.25 m. Aircraft navigation data were also recorded, simultaneous surface measurements, including wave slope, wave height, current, wind, and ship position, were obtained from the CFAV Endeavour. Current meter were located both fore and aft to allow internal wave-phase velocity estimates to be computed
