Radar Cross-Section (RCS) refers to the measure of how detectable an object is by radar. It is a critical factor in radar target detection and can be influenced by the shape, size, material, and orientation of the object. Stealth technology is designed to reduce an object’s RCS, making it less visible to radar systems. In military applications, reducing RCS is essential for aircraft and ships to avoid detection. Understanding RCS helps in designing radar systems that can effectively detect and track targets, whether for defense, surveillance, or environmental monitoring.
