Before the publication of this text, comprehensive information regarding Radar Cross Section (RCS) was scattered across academic journals, classified military reports, and obscure technical memos. Knott and his co-authors consolidated this knowledge into an accessible format.
A major portion of the work is dedicated to "beating the radar" through two primary methods:
Understanding how waves "bend" around sharp edges (Geometric Theory of Diffraction - GTD). 3. Absorbers and Material Treatments
The book details how to calculate the "echo" of a target using two main theoretical frameworks:
The search term reveals a community of learners and professionals who respect the foundations of stealth physics. While the allure of a free download is strong, remember that Knott spent decades refining these concepts.
Developing methods to quantify how objects reflect radar energy.
For rounded objects (like a sphere or a missile fuselage), waves can travel around the shadowed side of the object and reunite on the other side. Knott’s analysis of creeping waves highlights the complexity of RCS prediction, demonstrating that the "shadow" region of a target can still contribute to the radar echo.
