Introduction to Airborne Radar — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

This chapter gives the reasons. It begins by raising the fundamental question of exactly what is meant by the spectrum of a signal. This, as you'll see, is actually the crux of the matter. The chapter then explains the spectrum of a pulsed signal in two quite different ways: first, in terms of a conceptually simple but powerful analytical tool, called the Fourier series, and second, in terms of what physically takes place when a radio frequency signal passes through a lossless narrowband filter. For those readers who have some familiarity with calculus, the essence of both explanations is presented in more precise, mathematical terms - the Fourier transform - at the end of the chapter.
