The objective of this chapter is to present the considerations required in estimating the RCS of a complex target, data presentation formats, and data reduction. Topics to be covered are high-frequency scattering by a complex target - this is a discussion of the scattering mechanisms and phasor addition from multiple scattering centers; simple hip-pocket formulas for estimating scattering; RCS data requirements and presentation formats; RCS sector statistical characterizations, including examples of geometric and arithmetic averages.
