Developing High Resolution Atmospheric Phase Screens for Insar Time Series Analysis
نویسندگان
چکیده
The atmospheric artifacts in interferometric synthetic aperture radar (InSAR) measurements are a large error source in accurately estimating terrain deformation signals [1]. For example, the large magnitude, high spatial frequency atmospheric bubbles can easily be misinterpreted as deformation phenomena [2, 3]. Various InSAR time series techniques, such as the Permanent Scatterer (PS) and Small Baseline Subsets (SBAS) algorithms, estimate and remove atmospheric phase screens (APS) from the differential interferograms [4-6]. However, these time series techniques only estimate the low spatial frequency part of the atmospheric signals.

Mitigation of Tropospheric Delay on InSAR Interseismic Displacements
One of the major challenges of Interferometric Synthetic Aperture Radar (InSAR) technique is the existence of tropospheric effect on the results. The tropospheric effect is due to the changes of atmospheric parameters including temperature, pressure, and humidity between the master and slave images. In this research, two different methods based on spatial-temporal filters and calculation of pha...
متن کاملPersistent Scatterer localization and prediction technique
Synthetic aperture radar (SAR) Persistent Scatterer Interferometry (PS-InSAR) is an extension of the Differential Interferometry (D-InSAR). Using a large data stack consisting of a time-series of SAR images of the same area, stable reflectors which persist over a long period of time, the so-called Persistent Scatterers (PS), are determined and the phase shifts of these PS over time are measured...
متن کاملA noise model for InSAR time series
Interferometric synthetic aperture radar (InSAR) time series methods estimate the spatiotemporal evolution of surface deformation by incorporating information from multiple SAR interferograms. While various models have been developed to describe the interferometric phase and correlation statistics in individual interferograms, efforts to model the generalized covariance matrix that is directly ...
متن کاملA Statistical-cost Approach to Unwrapping the Phase of Insar Time Series
Fully 3-D phase-unwrapping algorithms are commonly based on the central assumption that the phase difference between neighbouring sample points in any dimension is generally less than half a phase cycle (the Nyquist criteria). In the case of InSAR time series, however, signals are correlated spatially but uncorrelated over the repeatpass time, due chiefly to changes in atmospheric delay. Here I...
متن کاملWater vapor observations with SAR, microwave radiometer and GPS: comparison of scaling characteristics
The knowledge of spatial distributions of water vapor is very important in atmospheric studies. Often satellite observations, for instance AVHRR, are used to study spatial distributions of water vapor. This method, however, has a limited spatial resolution of about 1 km and does not cover the entire atmospheric column. An alternative way to estimate the spatial behavior of the water vapor is to...
