Radar Cross Section

The Radar Cross Section (RCS) of an object is a measure of how easily it can be detected by radar. It quantifies how much radar energy the object reflects back to the radar receiver.

TECHNICAL DEFINITION

Radar Cross Section (RCS) is a metric quantifying the electromagnetic detectability of an object by radar systems, representing the hypothetical area required to intercept the same power as scattered by the actual target. It is influenced by the target's physical geometry, material composition, radar frequency, and aspect angle, and is a critical parameter in stealth technology and radar signature management.

BACKGROUND

The Saab Giraffe Radar is a family of land and naval two- or three-dimensional G/H-band passive electronically scanned array radar-based surveillance and air defense command and control systems. It is tailored for operations with medium- and Short Range Air Defense (SHORAD) missile or gun systems, or for use as gap-fillers in a larger air defense system.
