A Framework for Statistical Nonlocal Means Noise Reduction in PolSAR Data

Abstract

Fully Polarimetric SAR (Synthetic Aperture Radar), PolSAR, inherits the advantages of SAR systems (day and night imaging capacity, almost all-weather and active imaging), while extending its capabilities through the use of four polarization combinations (Horizontal and Vertical - HH, VV, HV, VH) [1]. PolSAR data integrates multiple types of rich information, such as frequency, amplitude and phase, which contributes to better characterizing different targets.
