Waves And Noise In SAR Imagery Of The Ocean
Abstract
Mikhail B. Kanevsky
The unified theory of SAR imagining of the ocean surface is presented in a concise form. The theory describes both the image of ocean waves and the speckle noise, which in the spectrum of the image appears as a pedestal under the spectrum of the waves themselves. Based on this theory, a spectral estimate is developed that does not use any a priori model of speckle noise and is free from speckle noise pedestal. Besides, the pedestal can be singled out and its shape can be visually shown in each particular case. Examples of applying the estimate using SAR data of ERS-2 and RADARSAT-2 are given.
