Book Description
This book deals with the fundamentals of stellar interferometry with emphasis on aperture synthesis using sparse array of telescopes particularly at optical/IR wavelengths, the origin, properties, and optical effects of turbulence in the Earth's atmosphere, techniques developed to overcome image degradation. Studded with more than one hundred and fifty illustrations and tens of footnotes, it addresses the basic tricks of trade, current trend, motivation, methods, and path to future promise of true interferometry both from the ground and space. Also discussed are the technical challenge involved, such as beam transportation and recombination, detecting fringes using modern sensors, and image synthesis. Astronomical science that benefits from aperture synthesis imaging are highlighted as well.

Book Description
Radio astronomy uses unique observational techniques and offers the only way to investigate many phenomena in the Universe. This book, by two founders of the field, presents both a clear introduction to radio telescopes and techniques, and a broad overview of the radio universe. The material in this new edition has been expanded and updated, reflecting the developments in the field over the last decade. New material reflects the increasing use of aperture synthesis and Very Long Baseline Interferometry, and the further exploitation of molecular spectral lines. A new chapter is devoted to the fundamentals of radiation and propagation theory. The second half of the book constitutes a review of radio observations of our Milky Way galaxy. Wide-ranging and clearly written, this book provides a thorough and up-to-date introduction to the subject for graduate students, and an invaluable overview for researchers turning to radio astronomy for the first time.

Book Description
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.

Book Description
The main purpose of this book is to serve as a university textbook for a first course in astronomy. However, we believe that the audience will also include many serious ama teurs, who often find the popular texts too trivial. The lack of a good handbook for am ateurs has become a problem lately, as more and more people are buying personal com puters and need exact, but comprehensible, mathematical formalism for their programs. The reader of this book is assumed to have only a standard high-school knowledge of mathematics and physics (as they are taught in Finland); everything more advanced is usually derived step by step from simple basic principles. The mathematical background needed includes plane trigonometry, basic differential and integral calculus, and (only in the chapter dealing with celestial mechanics) some vector calculus. Some mathematical concepts the reader may not be familiar with are briefly explained in the appendices or can be understood by studying the numerous exercises and examples. However, most of the book can be read with very little knowledge of mathematics, and even if the reader skips the mathematically more involved sections, (s)he should get a good overview of the field of astronomy. This book has evolved in the course of many years and through the work of several authors and editors. The first version consisted of lecture notes by one of the editors (Oja).
