Increasing information content is an important scientific problem in modern observation systems development. Radar, or microwave, imaging can be used for this purpose. The book provides an overview of the field and explains why a unified approach based on wave field processing techniques, including holographic and tomographic approaches, is necessary in high resolution radar design. It contains discussion of new areas in imaging radar theory, holographic radar, the questions of estimation and improving radar image quality, and finally various practical applications.

In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.

This volume contains the complete set of papers presented at the First U. S. -U. S. S. R. Sciences Cooperation Seminar on "Optical Information Processing" held at the U. S. National Academy of Sciences in Washington, D. C. from 16 - 20 June 1975 under the sponsorship of the National Science Foundation in cooperation with the U. S. S. R. Academy of Sciences. The papers present the latest theoretical advances and ex perimental state of the art in the newly developing field of "opti cal information processing", with particular emphasis on appli cations to communication, information storage and processing. Digital as well as optical systems are discussed in terms of concepts and implementations. Included are coherent and inco herent optical processing systems (for images and signals), materials and devices for optical computing, acousto-optic signal processing, memories (optical, digital and holographic), optical logic and optically-accessed digital stores, non-linear optical processing, as well as an analysis of the information capacity of optical processing systems and a report on new ex tensions of information processing in synthetic aperture radar. Detailed configurations and new manufacturing techniques for several components are presented, including such topics as "asymmetric interference fringes in reflected light" and' kino form optical elements" of very high quality; these are phase plates having a carefully controlled thickness, somewhat com parable to the famous Schmidt plates and which could have an important role in many optical computer and communications systems.

A guide to the applications of holographic techniques for microwave and millimeter wave imaging Real-Time Three-Dimensional Imaging of Dielectric Bodies Using Microwave/Millimeter Wave Holography offers an authoritative guide to the field of microwave holography for the specific application of imaging dielectric bodies. The authors—noted experts on the topic—review the early works in the area of optical and microwave holographic imaging and explore recent advances of the microwave and millimeter wave imaging techniques. These techniques are based on the measurement of both magnitude and phase over an aperture and then implementing digital image reconstruction. The book presents developments in the microwave holographic techniques for near-field imaging applications such as biomedical imaging and non-destructive testing of materials. The authors also examine novel holographic techniques to gain super-resolution or quantitative images. The book also includes a discussion of the capabilities and limitations of holographic reconstruction techniques and provides recommendations for overcoming many of the limitations. This important book: • Describes the evolution of wide-band microwave holography techniques from synthetic aperture radar principles • Explores two major approaches to near-field microwave holography: Using the incident field and Green's function information and using point-spread function of the imaging system • Introduces the "diffraction limit" in the resolution for techniques that are based on the Born approximation, and provides techniques to overcome this limit Written for students and research associates in microwave and millimeter wave engineering, Real-Time Three-Dimensional Imaging of Dielectric Bodies Using Microwave/Millimeter Wave Holography reviews microwave and millimeter-wave imaging techniques based on the holographic principles and provides information on the most current developments.

When Faraday performed the very first experiments on electromagnetic effects, which form the very foundation of modern civilization since virtually everything electrical utilizes them, he was asked of what use his experiments were. He is said to have replied: "What is the use of a baby?" That reply might also be given to those who asked what was the use of basic research which resulted in the development of the laser and holography. Brigadier General Leo A.Kiley, Commander, Office of Aerospace Research, USAF, in his remarks before the Society of Photo-Optical Instrumentation Engineers at the opening ceremony of the Seminar on Holography held at San Francisco, California, in May 1968, declared, "It has been said that in the twenty-first century at least half of the jobs that will exist then do not exist today. But be that as it may, I am sure that holography will be common place. " And later "Even in its embryonic state today, the concept of holography is providing real world applications to the scientific community and I feel that continued rapid growth can be predicted." Now, only three years after these statements, the development of holography is extraordinary on the scientific side and very promising from the point of view of proven and potential applica tions. Holography looks like an emerging technique, a valuable tool for engineers.
