Sample Essay

Give an example where saturation decoys are deployed rather than detection decoys. What are advantages and disadvantages of saturation and detection decoys?

Saturation decoys such as chaff are preferred choice for aircrafts and ship in case a missile has locked onto them. The use of saturation decoys confuses the missile about the availability of target, causing it to lose the lock. Saturation decoys offer advantage in situations where radar (such missile radar) has already detected and locked on to the target. However, it does not offer any guarantee if the radar will lose such as lock or not. Detection decoy on the other hand are used to make the radar detect the decoy rather than the real target. Hence, if a detection decoy is successful, it guarantees the safety of the target. However, the detection decoys do not have a 100% success rate and any failure of the decoy will leave the real target vulnerable (Adamy 225).

Explain the situation/application where you need to use a jammer rather than a decoy.

A jammer can be used in a situation in which a communication link between two points is required to be blocked. The decoys offer protection if the radar is focusing on them for detection, however, they are not of any use if the radar beam is focused on another target. In this scenario jamming is very effective as the jammer can be made to focus on the detection radar regardless of its location (Adamy 181).

 (b) What is meant by the term ‘Deinterleving’ in the context of a radar warning receiver?

De-Interleaving is a process in a Radar Warning Receiver in which different types of radar signals are separated from each other and active radar emitters are then detected from these signals(Cole).
