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...
SPATIO-SEMANTIC COHERENCE IN THE INTEGRATION OF 3D CITY MODELS
3D city models data integration 3D GIS spatio-semantic coherence semantic modelling GML CityGML
2015/9/28
An increasing number of applications rely on 3D geoinformation. In addition to 3D geometry, these applications particularly require complex semantic information. In the context of spatialdata infrastr...
Urban Change Detection Using Coherence and Intensity Characteristics of Multi-temporal ERS-1/2 Imagery
Change detection Urban area Long-term coherence variation
2015/8/20
In this paper, the potential of multitemporal ERS-1/2 InSAR data for detecting urban land-cover changes is investigated on a test
area within Shanghai city, China. A new unsupervised change-detection...
A method for monitoring hydrological conditions beneath herbaceous wetlands using multi-temporal ALOS PALSAR coherence data
Hydrological conditions Herbaceous wetlands Interferometric synthetic aperture radar (InSAR) Coherence Probability density function (PDF) Wet reeds extraction
2015/7/27
Reed marshes, the world’s most widespread type of wetland vegetation, are undergoing major changes as a result of climate changes and human activities. The presence or absence of water in reed marshes...
Spatial Coherence of winds and waves over the Arabian Sea and Bay of Bengal and their evolution during SW Monsoon: a novel application of along-track Radar Altimeter measurements from Space
Oceanic winds and waves spatial coherence SW Monsoon Radar Altimeter
2014/12/16
We have examined, for the first time, the spatial coherence of oceanic parameters, namely, the ocean surface wind and significant wave height (SWH), using near-instantaneous along-track sampling over ...
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...
