Radar cross section (RCS) is a measure of the return or scattering power in a given direction. Because of the chaﬀ cloud signal attenuation, the chaﬀ inside chaﬀ cloud can’t received signal energy like the chaﬀ near chaﬀ cloud surface, so the former’s RCS is smaller than the latter. WebIn radar passive countermeasure, chaff is used to for m the suppress jamming and center of mass jamming.
