Radar Cross Section Eugene F. Knott Pdf !link! <8K>

Explaining exactly how electromagnetic waves interact with simple shapes (spheres, cylinders, plates) and complex shapes (aircraft, ships).

Eugene F. Knott was a pioneer in the field of electromagnetics and radar scattering. His book Radar Cross Section (specifically the second edition published in 1993 and later revisions) is widely considered the "bible" of signature reduction.

Approximates the induced currents on the illuminated surface of a target to calculate the scattered field.

Unlike dense academic tomes, Knott’s work is celebrated for its accessibility. It begins with a full review of radar fundamentals and electromagnetic theory, ensuring that even a "novice can understand how radar echo requirements may influence design objectives". The text defines RCS simply as "a comparison of two radar signal strengths: the strength of the radar beam sweeping over a target versus the strength of the reflected echo".

Curved surfaces scatter energy widely, whereas flat surfaces perpendicular to the radar beam reflect massive amounts of energy directly back to the source.

Before building physical prototypes, engineers must predict RCS computationally. Knott's work covers both high-frequency approximations and exact solutions:

This report summarizes the seminal text by Eugene F. Knott , John F. Shaeffer, and Michael T. Tuley. First published in 1985 with a significantly expanded second edition in 1993, this book is considered a cornerstone for understanding how objects scatter radar energy. 1. Executive Summary
