Abstract: A method and system for detection of a target by a passive radar system exploiting multichannel-per-carrier cellular illuminator sources, the method including: receiving a reference signal from a reference source, said reference signal being received at a reference element of a radar receiver of the passive radar system; receiving, at a surveillance element of said radar receiver, a reflected signal originating from said reference source and reflected off the target, said reflected signal including interference; deciphering components of said signals; and reconstructing said signals, from said components, excluding said interference.
