Question

Eli5 How does detection of an incoming missile on aircraft work?

In: Technology

Answer 1

The target-finding radar of the missile or of the ground radar station guiding the missile can be detected (it‘s like listening to the noise of the missile engine, only at a different frequency „listening“ to the radar signals from the ground or the head of the missile). If the sensors detect these typical radar signals, they alert the crew.
