摘要

Ever since radar emerged as a primary means for surveillance, targeting and weapon guidance in the maritime arena, so navies have sought methods and means by which to disrupt or deceive potentially hostile radio frequency (RF) sensors. This specific subset of naval electronic warfare, historically referred to as electronic countermeasures (ECM) but latterly re-cast as electronic attack (EA), has two main objectives: first, to deny or disrupt radar picture compilation so as to degrade the ability of an adversary to make informed tactical decisions; second, to deceive or decoy the RF guidance and terminal homing systems used by the overwhelming majority of the world's anti-ship cruise missiles (ASCMs).Expendable RF countermeasures, such as chaff, corner reflectors and active offboard decoys, are an important part of the soft-kill armory. Such devices are popular owing to their relatively low cost, and the fact that they offer the inherent attraction of angular deception. Their principal drawbacks are limited endurance, the challenge of ensuring spectral realism, and the need for very accurate positioning in time and space in order to present a credible alternative target in the RF seeker field-of-view.
