Abstract
An improved chaff in which a plurality of metallic or metallic coated elets are joined as chain links that, when deployed, produce microarcs when the link elements make and break contact with each other in an electromagnet field such as that created by a high power radar transmitter. These microarcs will then in turn create current spikes that will reflect a radar signal that has a wider bandwidth than conventional chaff, so as to make it more difficult to distinguish the chain link chaff from a fast moving target such as an aircraft.
