What type of guidance does the AIM-9M Sidewinder utilize?

The AIM-9M Sidewinder utilizes passive infrared (IR) guidance, which makes it particularly effective in targeting heat signatures. This type of guidance system relies on the infrared radiation emitted by the target, usually from an aircraft's engines or other hot surfaces. When the Sidewinder is launched, its onboard guidance system tracks the thermal energy produced by the target.

This passive system allows the AIM-9M to engage targets without emitting radar signals, making it less detectable and providing a stealth advantage. In contrast, other guidance methods such as active radar or laser-guided systems involve different mechanisms that may not be as effective in all combat scenarios, especially in terms of engaging heat-emitting aerial targets in dynamic environments.
