Abstract:
Chaff plays an important role in U.S. penetration systems currently in use and being planned. Its purpose is to produce a clutter signal, in nature similar to noise, in a radar receiver that will mask the desired signal from the hard target, be it a re-entry vehicle or decoy. The degree of masking is ordinarily characterized by the received SN or signal-to-noise, i.e., chaff, ratio generally expressed in db, which is the difference between the scattering cross section of the body and that of the interfering chaff.
