Target Reflectivity
The basic motivation for this chapter is to describe a key link in the understanding of radar: how does a radar wave, more properly known as an electromagnetic (EM) wave, transmitted from some transmitter source, interact with a target to produce reflected energy at some receiver position? The goals for this chapter are as follows: 1. To understand what an electromagnetic wave is. 2. To understand its properties. 3. To describe a measure of the amount of reflected energy, a quantity known as radar cross section (RCS). 4. To understand basic scattering or reflectivity physics. 5. To focus on the typical microwave scattering mechanisms. 6. To understand how two or more scattering centers add and subtract. 7. To illustrate examples of high-frequency scattering from targets along with scattering center images.
