Radar cross-section (RCS) 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 of which the target is made; the size of the target relative to the wavelength of the illuminating radar signal; the absolute size of the target; the incident angle (angle at which the radar beam hits a particular portion of the target, which depends upon the shape of the target and its orientation to the radar source); the reflected angle (angle at which the reflected beam leaves the part of the target hit; it depends upon incident angle); the polarization of the transmitted and the received radiation with respect to the orientation of the target.
