Pulse Doppler Radar

The book is organized into three parts, each one building on the material of the previous sections. Part I (Chapters 1-8) covers the basic principles to lay sound foundations for the following parts of the book. It emphasizes classic processing techniques, especially the fast Fourier transform (FFT), and microwave engineering issues, antennas, and hardware. The second part of the book deals with the theory and techniques specific to pulse Doppler radar. This is subdivided into Part IIA (Chapters 9-10), which covers high PRF pulse Doppler, and Part IIB (Chapters 11-15), which covers medium PRF pulse Doppler. A major theme is that of PRF selection and optimization, other waveform design issues, and the problem of ghosting. While high and medium PRF pulse Doppler techniques have become synonymous with airborne fire control radars, they are used over a broad spectrum of airborne and surface-based radar applications. Part II does emphasize the airborne radar case, but it does not neglect the surface-based radar. Finally, Part III (Chapters 16-19) presents a series of four case studies. Each of these case studies applies the material of Part II whilst also highlighting additional radar techniques (and, in some cases, non-radar considerations) specific to the application. Such is the prevalence of pulse Doppler radars today; the number of case studies that could have been considered is well into double figures. However, the four presented here suffice to illustrate the wide variety of pulse Doppler radar applications.

This second edition of Airborne Pulsed Doppler Radar brings you up-to-date on new radar technologies since 1987 -- plus those likely to appear in the next five years. The book provides valuable insight into specific issues unique to airborne systems and contains the most extensive treatment of the medium-PRF waveform for more accurate performance analysis. Complete with nearly 250 illustrations and 290 equations, the book provides the background you need to: - Plan and predict the outcome of test programs - Evaluate proposals for new radar systems or upgrades - Analyze the performance of airborne radars in various scenarios - Understand the capabilities and limitations of airborne systems This book is a valuable reference for radar engineers, missile-seeker system engineers, and users of military airborne radar. It keeps you current on the fundamental principles and system design rationale for establishing radar characteristics, signal processing for target detection performance, and signal processing for tracking and system testing.

Presents the basic principles of pulse-doppler radar without resorting to a heavily mathematical treatment. High-, medium-, and low-pulse repetition frequency (PRF) modes are explained and the advantages and disadvantages of each are discussed. Also included are an explanation of the major signal-processing functions of doppler filtering, pulse compression, tracking, synthetic aperture, selection of medium PRFs, and resolving range ambiguities and a discussion of how to predict the performance of a pulse-doppler radar in the presence of noise and clutter.

Classical geometric optics estimates of the echo characteristics from both isotropic and directed acoustic shocks are presented together with the detection capability of a typical sensitive pulse Doppler radar (AFCRL Porcupine Doppler) in order to determine the feasibility of detecting large well defined boundaries of refractive index. Both the radar cross-section and the Doppler spectrum of an acoustic shock are sensitive to wind and temperature induced perturbations of the shock surface. For standard deviations in wind and temperature of 0.5 m/sec and 1C, the theoretical values of the maximum radar cross-section and minimum Doppler spectral width of a typical directed shock of 50 meters radius are found to be 0.0008 sq cm and 58 cps respectively. This target cross-section is about 6 dB stronger than the minimum cross-section detectable by the Porcupine radar at a range of only 1.8 kilometers. At this range, the presence of a weak signal may be completely masked by the presence of strong ground clutter signals. Signal processing techniques which improve the mean square to noise ratio and provide sub-clutter visibility are therefore crucial to the success of the experiment. Moreover, the sensitivity of the radar cross-section and the Doppler spectrum to wind and temperature perturbations restricts the experiments to calm conditions. (Author).
