Abstract

The disclosure relates to an electronic countermeasure cartridge ( 6 ) arranged to be loaded into a countermeasure dispenser ( 7 ) in a mobile platform ( 1 ). The electronic countermeasure cartridge ( 6 ) comprises an electromagnetic transmitting means ( 8 ), an electric energy storage ( 9 ) arranged to supply the electromagnetic transmitting means ( 8 ) with electric energy and a trigger device ( 10 ) arranged to trigger a transmission of electromagnetic radiation from the electromagnetic transmitting means ( 8 ) upon detection of an incoming threat ( 2 ). The transmitted electromagnetic radiation is arranged to irradiate an electromagnetically reflective material ( 3 ) dispensed from the countermeasure dispenser ( 7 ). The disclosure also relates to a method for providing threat protection for a platform ( 1 ) and to a countermeasure system comprising a countermeasure dispenser ( 7 ).
