Since the beginning of the IEEE GRSS society founded 54 years ago and the first IGARSS held in 1980, the GRSS tradition has been making our symposium worldwide. This is not only because of the global nature of our society, i.e. geosciences and remote sensing related, but also the GRSS leaders have an open mind to foresee fast advancement of remote sensing all over the world. We are very pleased that...
It is my distinct privilege to warmly welcome you to the International and Geoscience and Remote Sensing Symposium IGARSS 2016 in the historic and vibrant city of Beijing, China. IGARSS is the premier remote sensing conference organized by the IEEE Geoscience and Remote Sensing Society (GRSS) which provides the ideal forum for scientists, practitioners, and industries, as well as decision makers,...
On behalf of the Technical Program Committee (TPC), we would like to express our great pleasure in welcoming you all to IGARSS 2016 and hope you have a joyful stay in this historical, cultural, and beautiful modern cite of Beijing. We also express our appreciation to all the TPC members for their valuable contributions to the symposium.
Synthetic Aperture Radar (SAR) Tomography (TomoSAR) provides access to the three-dimensional (3D) structure of illuminated media by jointly focusing multiple SAR acquisitions. TomoSAR imaging can be understood in simple terms by considering that multiple SAR flight lines, or orbits, allow forming a bi-dimensional synthetic aperture, resulting in the possibility to resolve the targets not only in the...
The goal of this paper is to investigate the influence of temporal decorrelation on InSAR / Pol-INSAR and T-SAR in boreal forest. The P-, L-band Pol-InSAR data collected in campaign BioSAR 2008 was used in our study. The impact of temporal decorrelation on InSAR / Pol-InSAR and T-SAR is reflected by coherences, phases and vertical backscattering power. Markov model is applied to describe the quantitative...
This paper presents a study of the processing chain for ice and glacier structures in the holographic SAR tomography (HoloSAR) mode. The algorithm is mainly based on the fast factorized back-projection (FFBP) to solve a three-dimensional space using fully polarimetric data. The motivation of HoloSAR in the cryosphere is mainly driven by recent investigations that have shown the capabilities of this...
This work aims to describe the characteristics and the status of development, including the results of a first preliminary testing campaign, of a low frequency airborne imaging radar developed in Italy for the Italian Space Agency.
The SnowScat device is a ground-based stepped-frequency continuous-wave (SFCW) scatterometer supporting fully-polarimetric measurements within a frequency band from 9.2 to 17.8 GHz. It was originally designed to support the investigation and validation of Snow Water Equivalent (SWE) retrieval algorithms in the context of the development of the deselected COld REgions Hydrology High-resolution Observatory...
Forest above ground biomass (AGB) retrieval by TomoSAR technology has been preliminary studied over the last two years. Recent experiments have demonstrated that the backscattered power in HV channel at 30-m layer have strong correlation with the forest AGB, and be successfully used to build the estimation model. However, much progress remains necessary to make the best of the vertical distribution...
3D multibaseline SAR Tomography is emerging at the operational level for spaceborne monitoring of forest biomass, nevertheless problems still stands in particular about radiometric accuracy of the most diffused superresolution Capon processing. In this paper two alternative adaptive algoritms are proposed for Tomography, and tested by simulations and first P-band real data trials.
This paper focuses on the displacement Estimation and deformation monitoring experiment analysis based on Time series data. The experimental results demonstrate the validity and correctness of the methods in the paper, and the slope monitoring using ground based SAR is proved to be effective.
Systems based on Synthetic Aperture Radar Tomography at low frequencies offer 3D imaging capabilities, appropriate for forest monitoring. However the extraction of an ecologically meaningful measure of forest structure from the 3D reflectivity is not straightforward and several considerations need to be carefully taken into account, in order to avoid misinterpretations of the nature of the information...
