Application of Fractional Fourier Transform to Moving Target Indication via Along-Track Interferometry

A relatively unknown yet powerful technique, the so-called fractional Fourier transform (FrFT), is applied to SAR along-track interferometry (SAR-ATI) in order to estimate moving target parameters. By mapping ...

Filtering of Interferometric SAR Phase Images as a Fuzzy Matching-Pursuit Blind Estimation

We present an original application of fuzzy logic to restoration of phase images from interferometric synthetic aperture radar (InSAR), which are affected by zero-mean uncorrelated noise, whose variance depend...

Multichannel SAR Interferometry via Classical and Bayesian Estimation Techniques

Some multichannel synthetic aperture radar interferometric configurations are analyzed. Both across-track and along-track interferometric systems, allowing to recover the height profile of the ground or the mo...

Higher-Order Permanent Scatterers Analysis

The permanent scatterers (PS) technique is a multi-interferogram algorithm for DInSAR analyses developed in the late nineties to overcome the difficulties related to the conventional approach, namely, phase de...

Physics-Based Predictions for Coherent Change Detection Using X-Band Synthetic Aperture Radar

A theoretical model is developed to describe the interferometric coherency between pairs of SAR images of rough soil surfaces. The model is derived using a dyadic form for surface reflectivity in the Kirchhoff...

Analysis of Spaceborne Tandem Configurations for Complementing COSMO with SAR Interferometry

This paper analyses the possibility of using a fifth passive satellite for endowing the Italian COSMO-SkyMed constellation with cross- and along-track SAR interferometric capabilities, by using simultaneously ...

Spaceborne Polarimetric SAR Interferometry: Performance Analysis and Mission Concepts

We investigate multichannel imaging radar systems employing coherent combinations of polarimetry and interferometry (Pol-InSAR). Such systems are well suited for the extraction of bio- and geophysical paramete...

Joint Multi-baseline SAR Interferometry

We propose a technique to provide interferometry by combining multiple images of the same area. This technique differs from the multi-baseline approach in literature as (a) it exploits all the images simultane...

Multidimensional Speckle Noise Model

One of the main problems of SAR imagery is the presence of speckle noise, originated by the inherent coherent nature of this type of systems. For one-dimensional SAR systems it has been demonstrated that speck...

Model Order Selection in Multi-baseline Interferometric Radar Systems

Synthetic aperture radar interferometry (InSAR) is a powerful technique to derive three-dimensional terrain images. Interest is growing in exploiting the advanced multi-baseline mode of InSAR to solve layover ...
