Radar Cross Section (RCS) is a measure of how detectable an object is by radar, specifically defined as the comparison between the strength of the radar beam hitting a target and the strength of the reflected echo sensed by the receiver. The IET Shop The seminal work on this topic is the book "Radar Cross Section" Eugene F. Knott
Before diving into Knott’s work, one must understand the physics. Radar Cross Section (RCS) is a measure of how detectable an object is by radar. Formally, it is the hypothetical area required to intercept the transmitted power density at the target such that if the intercepted power were radiated isotropically, it would produce the observed echo density at the receiver. radar cross section eugene f. knott pdf
: For weapons system developers, the book provides deep technical detail on how to "beat" radar through two primary methods: Radar Cross Section (RCS) is a measure of
Every time you see the faceted surface of an F-117 Nighthawk or the smooth curves of a B-2 Spirit, you are seeing Eugene F. Knott’s theories in action. He provided the industry with the mathematical tools to quantify "stealthiness," moving it from a guessing game to a precise science. Knott’s theories in action
Practical RCS prediction workflow
By exploring Knott's resources and understanding the principles of RCS, you'll gain a deeper appreciation for the complexities of radar technology and its applications in various fields.
Eugene F. Knott ’s seminal work, Radar Cross Section , co-authored with John F. Schaeffer and Michael T. Tuley, is the definitive resource for understanding the echo characteristics of objects scanned by radar. First published as a set of course notes at Georgia Tech in 1983, the material was expanded into a comprehensive textbook that covers the prediction, measurement, and reduction of radar cross section (RCS).
