Evaluation of Filters for Envisat Asar Speckle Suppression in Pasture Area
In order to quantify real time pasture biomass from SAR image, regression model between ground measurements of biomass and ENVISAT ASAR backscattering coefficient should be built up. An important prerequisite of valid and accurate regression model is accurate grass backscattering coefficient which, however, cannot be obtained when there is speckle. Speckle noise is the best known problem of SAR...
متن کاملPasture Monitoring Using SAR with COSMO-SkyMed, ENVISAT ASAR, and ALOS PALSAR in Otway, Australia
Because of all-weather working ability, sensitivity to biomass and moisture, and high spatial resolution, Synthetic aperture radar (SAR) satellite images can perfectly complement optical images for pasture monitoring. This paper aims to examine the potential of the integration of COnstellation of small Satellites for the Mediterranean basin Observasion (COSMO-SkyMed), Environmental Satellite Ad...
متن کاملSnow Classification Algorithm for Envisat Asar
Capabilities and methods for snow mapping in mountainous areas using the Advanced Synthetic Aperture Radar (ASAR) on board of ENVISAT were investigated. For algorithm development the backscattering signatures of snow covered and snow free surfaces in Alpine valleys and on mountain slopes were studied with ASAR data of different look angles and polarizations in comparison with field measurements...
متن کاملNonlinear adaptive filters for speckle suppression in ultrasonic images
A novel approach to suppression of ultrasonic speckle based on a combination of segmentation and optimumLltering is presented. With the aid of a suitable modi cation of the Learning Vector Quantizer (LVQ) neural network, the image is segmented in regions of (approximately) homogeneous statistics. For each of the regions a minimum meansquared-error (MMSE) Llter is designed, by using the histogra...
متن کاملGeometric Performance of ENVISAT ASAR Products
We describe validation measurements of the geometric accuracy of ASAR images, measured redundantly via independent methods. Our tests include image (IM), alternating polarisation (AP), and wide swath (WS) mode acquisitions over a variety of test sites. ASAR's slant range products (IMS/APS) require a slightly different validation methodology than ground range precision (IMP, APP) and medium reso...
