Just as a mirror reflects light at a precise angle, smooth conductive surfaces reflect radar energy specularly. Knott emphasizes that the highest RCS peaks usually occur when the surface is normal (perpendicular) to the incident wave. This explains why a flat plate, when viewed directly from the front, creates a massive radar return, while a curved surface disperses that energy.
: It is described as a "fictitious area" equivalent to the size of a perfectly conducting sphere that would produce the same echo strength. radar cross section eugene f. knott pdf
: When the wavelength is comparable to the target size, causing "ringing" or oscillating RCS values. Optical Region Just as a mirror reflects light at a
Knott’s journey began at the , where he spent 16 years measuring lab models and developing early prediction models. A central theme of his work was bridging the gap between dense electromagnetic theory and "horse sense". Radar Cross Section (Radar, Sonar and Navigation) : It is described as a "fictitious area"
