Blog Post — Radar Cross Section and Eugene F. Knott: Foundations and Impact

Radar cross section (RCS) measures how detectable an object is by radar: it’s the equivalent area that would scatter the same amount of radar energy back to the receiver as the actual target. RCS depends on target size, shape, material, aspect angle, frequency, and polarization. Understanding RCS is central to radar system design, stealth technology, remote sensing, and signature management.

Radar cross section (RCS) is a measure of the amount of radar energy that is scattered back to the radar receiver from a target. It is a function of the target's size, shape, material, and orientation with respect to the radar wave. RCS is typically denoted by the symbol σ (sigma) and is measured in square meters (m²). The RCS of a target determines its detectability, tracking, and recognition by radar systems. radar cross section eugene f. knott pdf

What is Radar Cross Section (RCS)? A Quick Primer

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.

3. Creeping Waves

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. Understanding RCS is central to radar system design,
