An outstanding book on all aspects of passive and active intelligence collection across the electromagnetic spectrum and in other areas as well. This was used as a textbook for a graduate course I completed, and served as material for a course I helped develop for industry. This is an understanable, non-technical book on a technical topic, and is idel for systems engineers or those looking to expand their understanding in this area. Highly recommended for anyone working or interested in the show more field of technical intelligence collection. show less
