SAR calibration: A user's viewpoint
Abstract
The extent to which SEASAT SAR data meets user requirements is analyzed. The SAR system model is described. The user needs are illustrated by considering the problem of tracking and analyzing a 100 km wide storm located 1000 km from the SAR image. Required wave direction accuracy and wave number resolution are 1 deg and .002 fractional wave number. System resolution and radiometric response were studied using images of a corner reflector array. It is concluded that the SAR can measure well defined ocean swell systems with directional precision of 10 deg and wave number precision of 5%.
