If you have searched for the phrase , you are likely part of a specialized cohort: a graduate student cramming for a radar systems exam, an RF engineer designing a low-observable (LO) platform, or a defense analyst trying to understand how the F-35 or B-21 eludes detection.
Travelling waves that creep along the skin of an object and radiate energy when they hit a discontinuity, such as a trailing edge.
Knott provides the Physical Optics (PO) solution for a rectangular plate. Build this simulation. Then, rotate the plate. You will see the "specular spike" drop to near zero—this is exactly how stealth aircraft angle their surfaces. radar cross section eugene f. knott pdf
If you are working on a specific project, I can help you further if you tell me:
Low-frequency radars (HF/VHF) are the new counter-stealth threat. Knott’s earliest work in the 1970s covered the resonance region, which is exactly the frequency band where new Chinese and Russian radars claim to detect stealth jets. The old book is new again. If you have searched for the phrase ,
The text Radar Cross Section by Knott et al. is recognized for its thorough treatment of both fundamental theory and practical applications. It bridges the gap between complex electromagnetic theory and engineering practice, making it a staple in university courses and defense industries. Core Strengths of the Text:
When the first edition of Radar Cross Section was published (originally subtitled Its Prediction, Measurement, and Reduction ), the field of stealth technology was largely classified. Knott, alongside co-authors John F. Shaeffer and Michael T. Tuley, achieved the rare feat of translating complex electromagnetic warfare concepts into a digestible, academic framework. Build this simulation
To help tailor further information on radar physics, let me know:
where σ is the RCS, λ is the wavelength of the radar signal, E(θ,φ) is the electric field scattered by the target, and dΩ is the solid angle element.
Long before modern supercomputers could effortlessly run finite-element method (FEM) simulations, Knott detailed how engineers could predict RCS using high-frequency approximations. He thoroughly addresses:
Eugene F. Knott’s work on Radar Cross Section (RCS) is considered the "gold standard" for engineers, physicists, and defense researchers. If you are searching for a you are likely looking for the comprehensive technical insights found in his seminal textbook, Radar Cross Section , co-authored with John F. Shaeffer and Michael T. Tuley.
