(PDF) Radar Cross Section (RCS) Measurements - ResearchGate

Radar cross-section (RCS), also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: the material … See more Informally, the RCS of an object is the cross-sectional area of a perfectly reflecting sphere that would produce the same strength reflection as would the object in question. (Bigger sizes of this imaginary sphere … See more The size of a target's image on radar is measured by the radar cross section or RCS, often represented by the symbol σ and expressed in square meters. This does not equal geometric area. A perfectly conducting sphere of projected cross sectional area 1 m … See more RCS reduction is chiefly important in stealth technology for aircraft, missiles, ships, and other military vehicles. With smaller RCS, vehicles can better evade radar detection, … See more • System Planning Corporation • Electromagnetic modeling • Infrared signature • Survivability See more Size As a rule, the larger an object, the stronger its radar reflection and thus the greater its RCS. Also, radar of one band may not even detect certain size … See more Quantitatively, RCS is calculated in three-dimensions as Where See more For the case of an antenna the total RCS can be divided into two separate components as Structural Mode RCS and Antenna Mode RCS. The two components of the RCS relates to the two scattering phenomena that takes place at the antenna.

WebApr 16, 2024 · The glider can't hide the human inside. Extrapolating light aircraft RCS down to a glider, my best guess for the lowest-RCS gliders would be on the order of -10 to -5 dBsm, and no less than -12 dBsm or 0.05 m² due to the pilot. The reason is that a glider still contains a lot of non-radar-transparent parts, which will reflect radar frequencies ...
