High Frequency Over-the-Horizon Radar: Fundamental Principles, Signal Processing, and Practical Applications

A thorough and detailed treatment of the subject. Recommend.

Although there many journal articles and a Russian book on the subject translated by Barton, Fabrizio's book is the best, most comprehensive treatment of Over the Horizon Radar technology that I have seen.

Dr. Fabrizio has succeeded in writing a book that from the very outset engages the reader by making a highly complex topic seemingly simple and easy to understand. At the same time he has produced a comprehensive and up to date account of all aspects of HF over-the-horizon radar. The book takes a well-judged middle path, between a full and rigorous account of the underpinning mathematics and computational details and the intricacies of hardware design and implementation. This is supplemented through judicious use of references to the academic literature and useful accounts of a selection of real systems. This equips the reader to gain a detailed grasp of the key concepts and problems involved in end-to-end implementation. I fully expect this to become the "go to" text for all students and practitioners of HF radar for many a year to come. HIGH FREQUENCY OVER THE HORIZON RADAR: Fundamental Principles, Signal Processing, and Practical Applications

Perfetto e completo

By Dr. J R Barnum, WARF, SRI InternationalHardcoverAfter working with HF over-the-horizon radar (OTHR) for 40 years (1966-2006), it is my great pleasure that I was asked to review the comprehensive HF over-the-horizon radar book recently published by Dr. Giuseppe (Joe) Fabrizio from Australia. This indeed is an amazing volume. Through my interaction with Dr. Fabrizio during the drafting of his text, I must conclude that the author is a highly experienced and dedicated OTHR researcher and practitioner. I wholeheartedly agree with the previous Amazon reviews, particularly those from Scott C., Joseph Thomason, and Chris Baker.Indeed, I have been pleased to work closely with Australian HF radar enthusiasts since 1966, beginning at Stanford, then during subsequent technical exchange meetings. As discussed in the book, the WARF OTHR testbed was developed by Stanford in California during 1967 and demonstrated for the first time an ability for high spatial resolution with aircraft and ship detection. The WARF was transferred to SRI in 1970, after which time the greatest progress in OTHR was made, both in the U.S. and Australia. In particular, the U.S. Navy Relocatable OTHR (ROTHR) implemented four separate radar sites, patterned largely after WARF, three of which remain operable. The U.S., particularly SRI WARF, was pleased to transfer similar technology to Australia in the mid 1970’s, after which Australia developed the well-engineered Jindalee and multiple JORN OTHR systems. The WARF was decommissioned in 2006, following a joint experiment with visiting Australian engineers and the U.S. Naval Research Laboratory, who operated advanced digital HF receivers at mid CONUS field sites. With the HF high resolution technology firmly established, the advanced U.S. and Australian OTHR systems continue to flourish.Dr. Fabrizio has covered nearly every important research and development topic in OTHR that I am aware of. His mathematics are detailed enough to enable the reader to understand, apply, and push onward. His radar display examples are convincing proof that this technology actually works, in spite of highly variable (but nominally predictable and adaptable) ionospheric propagation conditions. I am especially impressed by the engineering emphasis on reducing low-frequency noise in the HF transmitters (which can cover up weak targets), and the excellent and timely digital technology developments in receivers and FMCW signal generators. The descriptions of adaptive signal processing are superb. Chapter 5, Surface-Wave Radar, is a very important addition, considering that this HF radar mode does not depend on variable ionospheric conditions, except insofar as near vertical incidence skywave (NVIS) clutter may add signal processing confusion (which can be mitigated through adept radar frequency management). The Bibliography and index are more extensive than I have every seen in an OTHR publication, which should give the student ample opportunity to explore any topic of interest. In that regard, I would suggest that the publisher recommend this book as a college text, or at least as required reference material for any course on HF radio propagation applications, most specifically OTHR.

Finally - a comprehensive state-of-the-art text for those of us interested in the long wavelengths at the left-hand side of the spectrum - and it's a great one! This 900-plus-page book is exclusively devoted to Over-the-Horizon Radar (OTHR) operating in the High Frequency (HF) band. By reflecting signals off the ionosphere, these phased-array radars are capable of surveilling very wide areas and detecting targets at very long ranges beyond the visual horizon.Somehow, at the same time, this book is both tutorial yet provides the depth necessary to benefit practicing scientists and engineers desiring to contribute to this expanding field. It fully describes the fundamental principles of operation at a level easily understandable for those new to this field, yet is packed with detailed descriptions of the relevant and state-of-the-art signal processing models and techniques. The book is also packed with real-data examples and experimental results that serve to demonstrate the real-world application of the signal processing techniques as they are introduced. In addition, the text contains a comprehensive bibliography close to 50 pages in length.While this book is a necessity for anyone interested or working in OTH radar, it will also be a useful addition to the library of any practicing radar engineer working at any frequency.

This 921 page book is the bible and reference book for Over Horizon Radar (OTH). It is extremely well written. It can be used by both the beginner and the practitioner in the field. It is written by a person who has hands on field experience and who as well has a deep knowledge of the theory re OTH systems, waveform design, signal processing and propagation. It is very well illustrated with clear figures which can be downloaded. Covers both sky and ground wave OTH in depth. Gives radar equation for both. Extensive real world system measurements and theoretical analysis. Covers modern signal processing techniques and systems such as adaptive beamforming, space-time-adaptive-processing (STAP), Likelihood Ratio Test (LRT), Generalized LRT (GLRT), Generalized Estimation of Multipath Signals (GEMS) algorithm as applied to blind waveform estimation, MUSIC. The book is a masterpiece. Should be must reading for all radar engineers. Dr. Eli Brookner (Lexington, MA, Raytheon, retired)

Good book
