So there are radio receivers on different parts of the plane. These can detect when radar hits them. Different radar systems do things differently so it can also tell the difference between different radar systems. It can tell when the aircraft has been locked on rather than just pinged by radar because a radar lock on is an intense beam of radar energy that continuously tracks the aircraft. So it’s constant and high powered. A radar lock does this so it can feed very accurate positional data to the weapon system. Normal radar, which will be sending out a wider beam and so less intense for anything it’s hitting on gives more general direction and range.

However, this doesn’t tell you anything if the system locking onto you using infrared (Heat Seeker) because that’s a passive system so nothing from that is hitting the plane. It’s just looking at the plane and detecting the plane’s heat.
