Communication and Radar Systems

by Nicolaos S Tzannes PhD

Overview

Communications and Radar Systems is the only book with a unique, unified approach for analyzing both Communication and Radar Systems at the pre-graduate level—a must for electrical engineering students or practicing engineers.

Chapters include: Introduction, Signal Analysis, Amplitude Modulation: Communication Systems, Amplitude Modulation: Radar Systems, Angle Modulation: Radar Systems, Analog Pulse Modulation: Communication Systems, Pulse Code Modulation: Communication Systems, Mixed Modulation: Radar Systems, Probability and Random Variables, Stochastic Processes, Noise in Communication Systems, Noise in Radar Systems, Electronic Warfare.

These chapter headings show the wide range of coverage of radar and communication systems. Written in a conversational style, Communication and Radar Systems is an easy-to-understand approach to radar and its relationship to communications systems.

Nicolaos S. Tzannes takes radar beyond its military uses into its many civilian applications, pointing out that the two fields have so much in common that the student with some prior background can absorb the material quickly and easily.
