MODEL ACCURACY COMPARISON FOR HIGH RESOLUTION INSAR COHERENCE STATISTICS OVER URBAN AREAS
Interferometric Synthetic Aperture Radar (InSAR) Coherence Statistics Model Accuracy Urban Areas
2016/11/24
The interferometric coherence map derived from the cross-correlation of two complex registered synthetic aperture radar (SAR) images is the reflection of imaged targets. In many applications, it can a...
THE EFFECT OF SPECKLE REDUCTION ON COHERENCE ESTIMATION AND INTERFEROMETRIC PHASE OF INSAR
SPECKLE REDUCTION COHERENCE ESTIMATION INTERFEROMETRIC PHASE OF INSAR
2015/12/30
Synthetic aperture radar (SAR) images always suffer from strongly speckle noise, which is a great obstacle to coherence (or correlation coefficient) estimation and interferometric phase, furthermore h...
STUDY ON RELATION BETWEEN INSAR COHERENCE AND SOIL MOISTURE
Coherence Soil moisture InSAR Interferometry De-correlation
2015/12/30
Coherence is an important parameter to measure InSAR data quality in repeat-pass interferometry and soil moisture change can cause de-correlation. Relation between coherence and soil moisture was exam...

POLINSAR Coherence-Based Regression Analysis of Forest Biomass Using RADARSAT-2 Datasets
Backscatter Complex coherence Forest biomass Polarimetric Interferometric SAR (POLINSAR)
2014/12/16
Forests play a pivotal role in synchronizing earth’s carbon cycle by absorbing carbon from the atmosphere and storing it in the form of biomass. Researchers today are trying to understand the climatic...
Classic approaches for the detection of flooded areas are based on a static analysis of optical images and/or SAR data during and after the event. In this paper, we aim to extract the flooded zones by...
