Written by a well-known expert in the field with more than 24 years of experience, this book explores electronic warfare (EW) applications and techniques and the radio frequency spectrum, with primary emphasis on high frequency to microwave. A detailed resource will help entry-level engineering personnel in EW, military personnel with no radio or communications engineering background, technicians and software professionals understand the basic concepts required for modeling and simulation, as well as fidelity and other practical aspects of simulation design and application. Clear explanations of important mathematical concepts, such as decibel notation and spherical trigonometry are provided. This informative reference explains how to facilitate the generation of realistic computer models of EW equipment. Moreover, it describes specific types of EW equipment, how they work and how each is mathematically modeled. The book concludes with a description of the various types of models and simulations and the ways they are applied to training and equipment testing tasks.
