Abstract :
Ripple in excess of that attributable to Gibb´s phenomenon has been identified in brightness temperature images created from data collected by synthetic aperture radiometers used for Earth remote sensing. The cause of the excess ripple is identified, and methods for reducing its effect on image quality are proposed
