RCS

RCS, or Radar Cross-Section, measures how detectable an object, like an aircraft, is by radar; a smaller RCS means the object is harder for radar to see.

TECHNICAL DEFINITION

Radar Cross-Section (RCS) is a quantitative measure of an object's detectability by radar, indicating the equivalent area of a perfect metallic sphere that would reflect the same amount of radar energy back to the receiver, and is a critical parameter in military aviation for designing stealth aircraft to minimize their radar signature.

SYNONYMS & ALIASES

  • Radar Signature
  • Radar Visibility
  • Stealth Profile
  • Radar Reflectivity

USAGE NOTE

In military aviation, engineers strive to reduce an aircraft's RCS through design and materials to enhance stealth capabilities.
