AIM-9 Missiles track their target using what technology?

The AIM-9 missile primarily uses infrared technology to track its target. This is significant because infrared homing allows the missile to detect and lock onto the heat signature of an aircraft, such as the engine exhaust, which is a critical feature for air-to-air combat.

Infrared guidance systems are highly effective for short-range engagements, making them well-suited for the AIM-9's designed purpose. The missile can home in on the target without relying on radar, which can be vulnerable to jamming and other electronic countermeasures. This capability enhances the missile's effectiveness in various combat scenarios, providing a stealthy approach that is difficult for enemy defenses to counter.

In contrast to the other option regarding radar, while radar systems depend on reflecting signals off a target, infrared utilizes the thermal emissions of the target, thus providing a different method of target engagement that is less susceptible to certain detection methods.
