deception jamming

deception jamming

deception jamming
Normal operation. The radar locks onto the target.
deception jamming
Aircraft on edge of beam. The jammer leaks into the antenna via the side lobe and the radar locks onto fake target.
deception jamming
The same process is repeated. Another fake target created.
An electronic countermeasure (ECM) operation whose aim is to deceive enemy sensors, especially radar. It involves transmitting fake return signals that the victim accepts as genuine. These signals often are sent when the enemy's antenna is not directly facing the jammer, so they must be very powerful to seep into the antenna via a side lobe. The fake pulse is then of an appropriate strength to be accepted as genuine.

It seems that the most effective solution is the use of laser-based IR jammers for deception jamming or simply to destroy the vulnerable parts of a missile's IR seeker.

Deception jamming is a technique in which an adversary would replicate one or more of the satellite ranging codes, navigation data signal(s) and carrier frequency Doppler effects with the intent of deceiving a victim receiver.
