The size of the target relative to the radar's wavelength alters the scattering behavior. This classifies scattering into three regions: Rayleigh (target is much smaller than wavelength), Resonance (target size matches wavelength), and Optical (target is much larger than wavelength).
The radar cross section (RCS) is a measure of how much electromagnetic radiation is scattered back to the radar receiver by a target. It's a fundamental concept in radar engineering, as it determines the detectability of a target by a radar system. RCS is typically denoted by the symbol σ (sigma) and is measured in square meters (m²). The size of the target relative to the
