Download or read book Microwave Indices from Active and Passive Sensors for Remote Sensing Applications written by Emanuele Santi and published by MDPI. This book was released on 2019-10-21 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Past research has comprehensively assessed the capabilities of satellite sensors operating at microwave frequencies, both active (SAR, scatterometers) and passive (radiometers), for the remote sensing of Earth’s surface. Besides brightness temperature and backscattering coefficient, microwave indices, defined as a combination of data collected at different frequencies and polarizations, revealed a good sensitivity to hydrological cycle parameters such as surface soil moisture, vegetation water content, and snow depth and its water equivalent. The differences between microwave backscattering and emission at more frequencies and polarizations have been well established in relation to these parameters, enabling operational retrieval algorithms based on microwave indices to be developed. This Special Issue aims at providing an overview of microwave signal capabilities in estimating the main land parameters of the hydrological cycle, e.g., soil moisture, vegetation water content, and snow water equivalent, on both local and global scales, with a particular focus on the applications of microwave indices.

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 400 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.

Download or read book Microwave Radar and Radiometric Remote Sensing written by and published by . This book was released on 2018-05 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave and millimeter wave high-power vacuum electron devices (VEDs) are essential elements in specialized military, scientific, medical and space applications. They can produce mega watts of power which would be equal to the power of thousands of solid state power devices (SSPDs). Similarly, in most of today's T/R-Modules of active phased array antennas for radars and electronic warfare applications GaAs based hybrid and MMIC amplifiers are used. The early applications of millimeter-wave MMICs were in military, space and astronomy systems. In the last three decades, microwave remote sensing has shown a high potential in characterization of land surface parameters (soil moisture, vegetation biomass, water covers, etc.). In this context, a very rich activity has been developed to propose techniques (satellite, airborne, in situ) and methodologies to optimize contribution of microwave remote sensing, in terms of precision, spatial, and temporal resolutions. Microwave Radar and Radiometric Remote Sensing provides you with theoretical models, system design and operation, and geoscientific applications of active and passive microwave remote sensing systems. It is aimed to the study of both reviews and original researches related to recent innovative microwave remote sensing instrumentation for land surface applications. Microwave remote sensing provides a unique capability towards achieving this goal. Over the past decade, significant progress has been made in microwave remote sensing of land processes through development of advanced airborne and space-borne microwave sensors, and the tools - such as physics-based models and advanced inversion algorithms - needed for analyzing the data. These activities have sharply increased in recent years since the launch of the ERS-1/2, JERS-1, and RADARS AT satellites, and with the availability of radiometric data from SSM/I. A new era has begun with the recent space missions ESA-ENVISAT, NASA-AQUA, and NASDA-ADEOSII, and the upcoming PALSAR and RADARSAT2 missions, which open new horizons for a wide range of operational microwave remote-sensing applications. This book highlights major activities and important results achieved in this area over the past years.

This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The power of microwave remote sensing for studying the oceans of the world was demonstrated conclusively by the SEASAT mission in 1978. Since then, no further satellite-flown instruments have been available to provide further data of this type. However, the proposed launch of ESA's ERS-1 satellite will lead to a new set of active microwave instruments being flown in space in 1990. Even though similar data has been obtained from aircraft-flown instruments SAR, scatterometers, altimeters etc. - a great deal of activity has been taking place to develop the necessary expertise in handling and analysing such data when it comes on-stream from ERS-1 and from subsequent satellites. It was against this background that the scientific Affairs Division of NATO again agreed to sponsor an ASI in Dundee in 1988. Its purpose was to review existing knowledge of the extraction of marine and atmospheric geophysical parameters from satellite-gathered microwave data and to enable scientists to prepare themselves and their computing systems to utilise the new data when it becomes available. The importance of the data is largely as input parameters to assist in the fitting of boundary conditions in large computer models. The course was concerned more with the non-imaging instruments, that is with passive radiometers, altimeters and scatterometers, than with the (imaging) synthetic aperture radar.

Book excerpt: "Techniques for gathering data by remote sensors on satellites utilized for sea ice research are summarized. Measurement of brightness temperatures by a passive microwave imager converted to maps of total sea ice concentration and to the areal fractions covered by first year and multiyear ice are described. Several ancillary observations, especially by means of automatic data buoys and submarines equipped with upward looking sonars, are needed to improve the validation and interpretation of satellite data. The design and performance characteristics of the Navy's Special Sensor Microwave Imager, expected to be in orbit in late 1985, are described. It is recommended that data from that instrument be processed to a form suitable for research applications and archived in a readily accessible form. The sea ice data products required for research purposes are described and recommendations for their archival and distribution to the scientific community are presented."--NTIS abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Passive Microwave Remote Sensing of Oceans Igor V. Cherny and Victor Yu. Raizer In Passive Microwave Remote Sensing of Oceans, the detailed results of more than 20 years of experimental and theoretical investigations in the field of ocean remote sensing, utilising microwave radiometric techniques and multi-frequency aerospace instruments, are presented. Experimental results presented in this book to some extent contradict the traditional view that microwave radiometry and, in particular, millimetre-wave frequencies are not useful for remote sensing of oceans. The authors show that studies of the ocean and atmosphere as a coupled system, and of processes occurring at the ocean surface and in deep water, can be reliably evolved using compact passive radiometric sensors. They further demonstrate that for studies of global, large-scale and local processes in the ocean-atmosphere system, only the combination of microwave and optical techniques will reveal the spatial structure and dynamics of the ocean surface at scales from centimetres to several hundred metres. The text first introduces ocean surface phenomena, discussing the ocean-atmosphere interface, the classification of surface waves, the generation and statistics of wind waves, and wave-breaking and foaming processes. The microwave emission characteristics of the ocean surface are then described, and the influence of wind waves, bubble-foam-spray coverage, oil spills and sea ice are discussed. The instruments and methods used for passive microwave remote sensing of the oceans from both aircraft and from satellites are reviewed. Microwave observations of processes in the ocean-atmosphere system are then described in detail, incorporating a new approach for microwave diagnostics of deep-ocean processes. Examples presented include the Rossby soliton, frontal zone in the Kurosio region, influence of brief showers on the subsurface layer, and interaction of tropical cyclones with the ocean during their origin and subsequent trajectories over the ocean surface. Readership: Undergraduate and postgraduate students studying remote sensing, marine science, oceanography, geography, geophysics, meteorology, climatology, atmospheric physics and environmental science. Professional oceanographers and those interested in oceanographic remote sensing processes and their applications, marine scientists and engineers, environmental scientists, and those studying the ocean-atmosphere system.
