: Detailed guidance on reducing target echoes through both shaping (altering geometry to deflect waves) and absorption (using RAM).

Eugene F. Knott is a renowned expert in the field of radar cross section prediction. He has authored numerous papers and books on the subject, including the seminal book "Radar Cross Section" (co-authored with John F. Shaeffer and Michael T. Knott). Knott's work has focused on developing analytical and numerical methods for predicting the RCS of complex targets.

It offers concrete examples, such as the RCS of a sphere, which is independent of frequency at high frequencies (where the radius is much larger than the wavelength).

Radar cross section (RCS) is a measure of the amount of radar signal that is reflected back to the radar receiver from a target. It is a function of the target's shape, size, material, and orientation with respect to the radar. RCS is typically denoted by the symbol σ (sigma) and is measured in square meters (m²). A higher RCS indicates that a target is more detectable by radar, while a lower RCS indicates that a target is less detectable.

The text covers everything from the fundamental definition of RCS to advanced concepts like edge scattering, surface waves, and traveling waves.
