GB‐InSAR interferogram processing method to generate DEM based on PS technology

Research on a Correction Method to Existing Grid-based Dem

The existing grid-based DEM has several disadvantages in representing the features of real terrain surface, such as peak clipping, channel filling, etc. And abrupt changes in elevation cannot be handled easily and precisely. The inherent size of grid mesh affects the DEM computing, analysis and results. Through the discussion of DEM terrain distortion, the representative types of distortion wer...

Microbial Fuel Cell: A New Alternative Technology to Generate Electricity from Organic Matter

The study of Interferogram denoising method Based on Empirical Mode Decomposition

This paper proposes a new filter based on empirical mode decomposition that is based on different characteristics of signal with noise in different IMFS for suppressing speckle in SAR interferogram is proposed. At first empirical mode decomposition is used to divide signal and processed high-frequency IMF signals separately by adaptive filter. The denoising effect of the proposed method, usual ...

Ps Processing with Decorrelating Targets

The strength of PS SAR interferometry stays with the availability of point-like targets coherent over many years [2]. In a previous work [4] we have investigated the possibility of extending the analysis to targets showing less ideal scattering properties, through the introduction of a covariance matrix estimated from the radar images. However since it is applied to a late phase of the processi...

Improved Goldstein Interferogram Filter Based on Local Fringe Frequency Estimation

The quality of an interferogram, which is limited by various phase noise, will greatly affect the further processes of InSAR, such as phase unwrapping. Interferometric SAR (InSAR) geophysical measurements', such as height or displacement, phase filtering is therefore an essential step. In this work, an improved Goldstein interferogram filter is proposed to suppress the phase noise while preserv...
