WebThe radar cross section (RCS) of a target is the equivalent area seen by a radar. It is the fictitious area intercepting that amount of power which, when scattered equally in all directions, produces an echo at the radar equal to that from the target. Mathematically, it is written as: (10.8) where: • R = distance between radar and target • WebAnechoic chambers test smaller spiral and sinuous antennas: Frequencies from 0.5 GHz up to 100 GHz.
