When the target's physical dimensions are roughly equal to the radar wavelength, the electromagnetic waves create surface traveling waves that wrap around the object. These waves interfere constructively or destructively, causing the RCS value to oscillate violently with minor changes in frequency or target size. 3. The Optical Region (
Many of his early technical reports for the Department of Defense are hosted here for public access.
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. radar cross section eugene f. knott pdf
RCS is rarely a constant; it fluctuates based on the target’s physical shape, the frequency of the radar, the polarization of the signal, and the aspect angle at which the radar "sees" the object.
