Preface.
The first version of this book was written in the late 1960s. At that time the relationships between the radar waveform, the carrier frequency, the signal processing, and the environment were understood well enough to project some highly capable systems. The digital age was just beginning, but implementation was still cumbersome and expensive. During the late 1970s and early 1980s a number of sophisticated but highly successful radars were developed using the
knowledge of the environment to select the waveforms and taking advantage of the rapid progress in digital technology.
As the 1980s evolved, radar was beginning to be called a mature technology until the Exocet missile, stealth targets, sophisticated electronic countersurveillance measures (ECM), drug interdiction requirements, etc. , demanded a new look at radar design and technology. This in tu requires further knowledge of the details of target reflectivity, natural clutter and clutter artifacts, and a radar’s susceptibility to electronic interference. The potential of remote sensing
and space-based radars also requires a better understanding of the environment and signal processing.
Thus the emphasis of this book is on radar design to cope with the total environment rather than any single performance goal. The total enviroment, as defined here, includes the unwanted reflections from the sea, land areas, precipitation, and chaff, as well as thermal noise and jamming. It also recognizes that mapping, weather sensing, terrain avoidance, altimetry, etc. , may be designed for a single-function radar or as modes of a multifunction radar.
As in the first edition, the book is divided into three parts. The first four chapters contain an introduction to radar; expanded material on the fundamentals of antennas, transmitters, multipath and ducting problems; and a review of the radar equations for the detection of
targets in the presence of noise and natural and man-made interference. This is followed by descriptions of the statistics of target detection and the techniques for obtaining automatic detection with considerable new material on advanced constant false alarm techniques and trackbefore-detect.
Chapter 5 contains a mostly new and thorough survey and analysis of the available material on the reflectivity of both natural and manmade targets. It includes the spectral, polarization, and wavelength properties since they all have been shown to have a substantial effect on the choice of processing technique.
Chapter 6 contains greatly expanded material on propagation and the reflectivity from precipitation and chaff. This includes statistics on their occurrence, carrier-frequency selection, and frequency-agility effects, wind shear phenomena, the bright band, anomalous echoes, etc. with statistical descriptors to evaluate signal-processing techniques.
Chapter 7 follows in the same format to describe sea and land clutter with new models, and statistical descriptions that must be included when analyzing highresolution radar detection of low-flying targets. Reflectivity is related to carrier frequency, polarization, and ducting effects. Bistatic data are included.
Chapters 8 through 13 contain descriptions of the various signalprocessing techniques that are widely used or proposed for future radar systems. After a general discussion of processing concepts, specific techniques are discussed for the detection of moving targets by use of the Doppler effect (CW, MTI, pulse Doppler), FFTs, and fast convolvers and the pulse compression techniques (phase-coding, frequency-coding, and linear FM). In most of these signal-processing chapters there is a discussion of the theory of operation, and diagrams of typical processors with emphasis on the new digital implementations and the limitations and losses. The equations for performance evaluation, along with advantages and disadvantages of each technique, are generally included.
Chapter 14 describes some newer or more specialized techniques such as the moving target detector (MTD) and clutter maps; ground, airboe, and space-based meteorological radars often using pulse-pair processors; and surveillance radars on aerostats. The final section contains a description on how to analyze or simulate coherent radars including the limitations and related loss terms.
It is not suggested that there is an optimum radar or even a generally optimum waveform, but that in the impending era of adaptive radar, the radar will sense the environment and adapt to this information. While not specifically written as a textbook, the earlier edition was used for a number of graduate courses on radar and in many intensive short courses. An attempt has been made to better organize the material, while retaining the chapter structure for those familiar with the first edition. Supplementary material and further derivations are available in the 800 references.
