radar cross section[′rā‚där ′krȯs ‚sek·shən]
radar cross section (RCS)
The measure of reflectivity of the received radar signals by an aircraft, it is expressed as square meters (m2). It is dependent on the true size, range, aspect, geometric shape, materials, surface texture, and other properties of the target aircraft. The most important element is the target aspect [i.e., the area normal (perpendicular) to the radar axis]. The higher the area, the greater the RCS.
