A decoy for protecting a platform (such as an aircraft) against radar based threats comprises an ejectable unit, ejectable from a launch tube on the platform. The ejectable unit comprised memory means 12 having predetermined information loaded on it relating to potential threats. The unit further comprises an antenna 11 for receiving and transmitting RF signals and signal processing means 15 for processing received RF signals. Comparing means compare the processed signals with the predetermined information and determine the presence of a threat. On determining a threat, the signal processing means 15 transmits an altered RF signal via the antenna 11 such that the received signal is jammed and the threat is lured away from the platform. |
