Polarimetric SAR speckle noise model [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2003
Synthetic aperture radar (SAR) data are affected by speckle noise, originated by the SAR system's coherent nature. The problem of speckle noise in one-dimensional (1-D) data is already solved, as speckle has a multiplicative characteristic.

Laser speckle imaging with an active noise reduction scheme [PDF]

Optics Express, 2005
We present an optical scheme to actively suppress statistical noise in Laser Speckle Imaging (LSI). This is achieved by illuminating the object surface through a diffuser.
