First published in 2004. Ce livre fait le point sur les applications du radar, tant aeroporte que spatial, en cartographie. La cartographie topographique est le sujet principal de l'ouvrage qui se concentre en particulier sur la modelisation numerique de terrain par radargrammetrie, radarclinometrie et interferometrie. Les principales applications thematiques de l'imagerie radar sont egalement passees en revue et illustrees_. Destine aux utilisateurs et aux etudiants interesses par le domaine de l'imagerie radar (topographes, ingenieurs civils, geologues ... ) ce texte les informera sur les potentialites - et les Ii mites - de cette technique.

Synthetic aperture radar provides broad-area imaging at high resolutions, which is used in applications such as environmental monitoring, earth-resource mapping, and military systems. This book presents the tools required for the digital processing of synthetic aperture radar images. They are of three types: (a) the elements of physics, (b) mathematical models and (c) image processing methods adapted to particular applications.

The special interest in electronics all over the world is due to its decisive role in the scien tific and technical progress now taking place in all fields of modern technology. Electronics also plays a decisive role in the development of science, providing as it does the technical basis for various scientific experiments. The role of electronics in the development of the world's culture also deserves a special mention. That is why it is hoped that the English-German French-Dutch-Russian Dictionary of Electronics, which contains some 9.000 entries and is jointly published by Kluwer Technische Boeken, B.V. (Deventer, Holland) and Ruski Yazyk Publishers (Moscow, USSR) will be favourably received. In accordance with existing international tradition, the term «electronics» covers several fields known in Soviet classification as elec tronics proper, radio engineering, and wire communication. The entries included in this dictionary have been selected in accordance with the international understanding of the term «electronics». One of the main difficulties encountered by the compilers was that although according to some calculations the number of terms used in special literature on electronics exceeds 50.000, the vocabulary of the dictionary had to be restricted to only 9.000 entries. Therefore this dictionary cannot claim to be comprehensive. Its purpose is to enable a wide range of specialists in various countries to find the English, German, French, Dutch, or Russian equivalents of the principal and most up-to-date terms in the field of electronics. Most attention has been paid to quantum electronics, fibre optics, optoelectronics, integrated circuit technology, radiolocation and radionavigation, pulse technique, holography, etc.

Containing useful information sources for the management of natural resources, this comprehensive text covers a large range of spatial resolutions and spectral characteristics. The book deals with the data sources and their physical interpretation, as well as processing techniques, such as visual interpretation and automated classifications, textural and structural processing and photogrammetry. There is a section on accuracy assessment and various applications relating to crops, grasslands, soils, landscapes, mines and coasts. The CD-ROM contains software and image data sets explaining the statistical methods of reference and contains a light version of the TeraVue software enabling the reader to compute the different processing spatial data.

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.

Using numerous operational and research-oriented examples, this text seeks to explain how the human eye and brain can extract and use remotely sensed data in the fields of applied geology and mineral exploration.

The cryosphere, that region of the world where water is temporarily or permanently frozen, plays a crucial role on our planet. Recent developments in remote sensing techniques, and the acquisition of new data sets, have resulted in significant advances in our understanding of all components of the cryosphere and its processes. This book, based on contributions from 40 leading experts, offers a comprehensive and authoritative overview of the methods, techniques and recent advances in applications of remote sensing of the cryosphere. Examples of the topics covered include: • snow extent, depth, grain-size and impurities • surface and subsurface melting • glaciers • accumulation over the Greenland and Antarctica ice sheets • ice thickness and velocities • gravimetric measurements from space • sea, lake and river ice • frozen ground and permafrost • fieldwork activities • recent and future cryosphere-oriented missions and experiments All figures are in color and provide an excellent visual accompaniment to the technical and scientific aspect of the book. Readership: Senior undergraduates, Masters and PhD Students, PostDocs and Researchers in cryosphere science and remote sensing. Remote Sensing of the Cryosphere is the significant first volume in the new Cryosphere Science Series. This new series comprises volumes that are at the cutting edge of new research, or provide focussed interdisciplinary reviews of key aspects of the science.
