14.2 Multiple-Look Processing
The appearance of speckle in a SAR scene, or multiplicative image noise, as
described before, can be reduced using a technique known as multi-look processing.
The concept of multi-look processing is SAR is a relatively simple one, whereby the
along-track beam, Doppler bandwidth (Ren et al. 2002) is filtered into a number of
