Radar Signals An — Introduction To Theory And Application Artech House Radar Library

In conclusion, Radar Signals: An Introduction to Theory and Application succeeds magnificently in its stated goal. It teaches the reader to think in terms of the ambiguity function, to evaluate waveforms by their sidelobe structure and resolution cells, and to appreciate the fundamental information-theoretic limits of radar measurements. For the practicing radar engineer, graduate student, or researcher, this book is not merely a reference—it is a lens through which the entire radar system becomes coherent. The signals are not just the message; they are the medium, the method, and the measure of radar’s profound ability to see what cannot be seen. Note: This essay assumes the canonical content of the Artech House Radar Library volume commonly known by this title (authored by Nadav Levanon and/or Eli Mozeson in many editions). If you have a specific edition or author in mind, the focus can be adjusted further.

A notable strength of Radar Signals is its treatment of Doppler-tolerant waveforms. Unlike many introductory texts that treat moving targets as an afterthought, this book integrates Doppler effects into every waveform analysis. It distinguishes between the slow-time Doppler processing of pulse-Doppler radars and the fast-time effects that degrade matched filter performance. The comparison of LFM (moderately Doppler tolerant) with phase-coded waveforms (often severely Doppler sensitive) is handled with practical examples, including ambiguity function cuts that reveal how target velocity can cause range sidelobe inflation or even target eclipsing. This analysis directly supports the design of radar modes for different missions—from slow-moving weather targets to supersonic aircraft. In conclusion, Radar Signals: An Introduction to Theory

The central thesis of the book is that the transmitted signal is the radar’s primary degree of freedom. While antenna design and receiver sensitivity are critical, the waveform determines fundamental performance limits in range resolution, Doppler sensitivity, and interference rejection. The text opens by grounding the reader in the necessary mathematical foundations—linear systems, modulation theory, and statistical signal processing—before launching into the core of the matter: the ambiguity function. This two-dimensional representation of a waveform’s response to range and Doppler shifts is presented not as an abstract curiosity but as a design blueprint. The book meticulously demonstrates how a simple rectangular pulse offers excellent range resolution only at the expense of poor Doppler discrimination, while a continuous wave (CW) tone provides the opposite. The genius of the text lies in showing how more complex signals, such as linear frequency modulated (LFM) chirps and phase-coded sequences (Barker, Frank, and Golomb codes), can shape the ambiguity function to approximate the ideal “thumbtack” response—high resolution in both dimensions without ambiguous sidelobes. The signals are not just the message; they

However, the book is not without its limitations. Its depth—while a strength for specialists—may be daunting for an undergraduate or a non-signal-processing engineer. The mathematical prerequisites are significant: Fourier transforms, complex envelope representation, and basic probability are assumed. Furthermore, the book focuses almost exclusively on monostatic pulsed radars, with only cursory mention of continuous wave, FMCW, or passive radar systems. Modern topics such as MIMO radar waveforms, cognitive radar, and machine learning for signal classification are absent, reflecting the publication date of earlier editions, though the core principles remain timeless.
