1.6 Radar Literature

This text covers a middle ground in radar technology. It focuses on basic radar
signal processing from a digital signal processing point of view. It does not
address radar systems, components, or phenomenology in any great depth except
where needed to explain the signal processing aspects; nor does it provide in-
depth coverage of advanced radar signal processing specialties. Fortunately,
there are many excellent radar reference books that address both needs. Good

books appear every year; those listed in the paragraphs that follow are current
as of the year 2013.

1.6.1 Radar Systems and Components
Probably the most classic introductory text to radar systems, now in its third
edition, is by Skolnik (2001). The newest and one of the best “radar 101”
introductions is the new text by Richards et al. (2010), the first of a three-

volume series. The 1990s saw the introduction of several general radar system
textbooks. The text by Edde (1995) also has an associated self-study course.
Peebles (1998) provides a recent, comprehensive introduction, while Mahafza
®
(2000) provides a number of useful MATLAB files to aid in simulation and
experimentation. Morris and Harkness (1996) provides a good introduction to
airborne pulsed Doppler systems specifically. A newer discussion of pulsed
Doppler systems is given by Alabaster (2012). An up-to-date survey of a broad

range of traditional and modern radar applications is given in Scheer and
Melvin (2014), showing how many of the techniques discussed in both these
introductory texts and the more specialized ones discussed below are brought
together into complete systems.
