This book presents systematised results on the application of direct and inverse aperture synthesis for radar imaging by holographic and tomographic techniques. The focus is on the research data obtained by the authors themselves. The book is primarily intended for engineers, designers and researchers, who are working in radar design and maintenance and are interested in the fundamental problem of extracting useful information from radar data.
