Download or read book SAR Temporal Series Interpretation and Backscattering Modelling for Maize Growth Monitoring written by Éric Auquière and published by Presses univ. de Louvain. This book was released on 2001 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research objective is to develop a methodology for the extraction of bio- and geophysical variables from Synthetic Aperture Radars (SAR) and for their use in the perspective of maize monitoring in an operational context. SARs interest agronomists because they present some advantages for vegetation monitoring. However, the actual revisit cycle of SARs is not sufficient for crop monitoring. The image processing chain we developed overcomes this issue and meets the 4 requirements for operational crop monitoring: a high temporal resolution, a high geometric accuracy, a short processing time and the preservation of the signal content. From the literature, we know that the interactions between the signal backscattered by the vegetation and by the underlying soil are very complex. To understand these interactions, we carried out very intensive ground campaigns. The resulting data set is very rich. It covers 3 growing seasons during which 30 ERS SAR images and 13 RADARSAT SAR images were acquired and processed. In total, 612 fields, i.e. 581 maize fields and 31 sugar beet fields were located and visited. These field campaigns represent 2500 field visits and more or less 7500 measurements of 8 variables. One of the major outputs of this research comes from the analysis of the temporal behaviour of the SAR signal distribution at both field and regional levels. The SAR signal is analysed by the mean of the per-field backscattering coefficient. Previous results concerning the respective contribution of soil and crop are confirmed. The research also addresses the use of several regional indicators. We point out a drop of per-field variation coefficient averaged at regional level and we link it to the decrease of the infra-parcel variability of the soil roughness and to the progressive masking effect of the crop canopy on different sources of variability. The spatial variability of the ERS per-field backscattering coefficients is related to the variability of the sowing dates. Finally, existing and new versions of the cloud model are calibrated and validated. The cloud model is adapted to account for the data available from the field campaigns. The results show that SAR do not allow the prediction of the maize biomass at the field level but they can be used to give an indication on the crop status at a regional level.

Book excerpt: The recent launches of three fully polarimetric synthetic aperture radar (PolSAR) satellites have shown that polarimetric radar imaging can provide abundant data on the Earth’s environment, such as biomass and forest height estimation, snow cover mapping, glacier monitoring, and damage assessment. Written by two of the most recognized leaders in this field, Polarimetric Radar Imaging: From Basics to Applications presents polarimetric radar imaging and processing techniques and shows how to develop remote sensing applications using PolSAR imaging radar. The book provides a substantial and balanced introduction to the basic theory and advanced concepts of polarimetric scattering mechanisms, speckle statistics and speckle filtering, polarimetric information analysis and extraction techniques, and applications typical to radar polarimetric remote sensing. It explains the importance of wave polarization theory and the speckle phenomenon in the information retrieval problem of microwave imaging and inverse scattering. The authors demonstrate how to devise intelligent information extraction algorithms for remote sensing applications. They also describe more advanced polarimetric analysis techniques for polarimetric target decompositions, polarization orientation effects, polarimetric scattering modeling, speckle filtering, terrain and forest classification, manmade target analysis, and PolSAR interferometry. With sample PolSAR data sets and software available for download, this self-contained, hands-on book encourages you to analyze space-borne and airborne PolSAR and polarimetric interferometric SAR (Pol-InSAR) data and then develop applications using this data.

Download or read book Polarimetric Synthetic Aperture Radar written by Irena Hajnsek and published by Springer Nature. This book was released on 2021-03-24 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book focuses on the practical application of electromagnetic polarimetry principles in Earth remote sensing with an educational purpose. In the last decade, the operations from fully polarimetric synthetic aperture radar such as the Japanese ALOS/PalSAR, the Canadian Radarsat-2 and the German TerraSAR-X and their easy data access for scientific use have developed further the research and data applications at L,C and X band. As a consequence, the wider distribution of polarimetric data sets across the remote sensing community boosted activity and development in polarimetric SAR applications, also in view of future missions. Numerous experiments with real data from spaceborne platforms are shown, with the aim of giving an up-to-date and complete treatment of the unique benefits of fully polarimetric synthetic aperture radar data in five different domains: forest, agriculture, cryosphere, urban and oceans.
Download or read book Introduction to Microwave Remote Sensing written by Iain H. Woodhouse and published by CRC Press. This book was released on 2017-07-12 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Microwave Remote Sensing offers an extensive overview of this versatile and extremely precise technology for technically oriented undergraduates and graduate students. This textbook emphasizes an important shift in conceptualization and directs it toward students with prior knowledge of optical remote sensing: the author dispels any linkage between microwave and optical remote sensing. Instead, he constructs the concept of microwave remote sensing by comparing it to the process of audio perception, explaining the workings of the ear as a metaphor for microwave instrumentation. This volume takes an “application-driven” approach. Instead of describing the technology and then its uses, this textbook justifies the need for measurement then explains how microwave technology addresses this need. Following a brief summary of the field and a history of the use of microwaves, the book explores the physical properties of microwaves and the polarimetric properties of electromagnetic waves. It examines the interaction of microwaves with matter, analyzes passive atmospheric and passive surface measurements, and describes the operation of altimeters and scatterometers. The textbook concludes by explaining how high resolution images are created using radars, and how techniques of interferometry can be applied to both passive and active sensors.
