Which type of terminal homing uses an external illumination source?

Explanation:
External illumination in terminal guidance is provided by an outside source. In semi-active terminal homing, the target is illuminated by a designator or fire-control radar from another platform; the missile’s seeker then detects the reflections of that energy off the target and uses them to steer to impact. This relies on energy coming from outside the missile, unlike active guidance where the missile itself emits energy to illuminate the target, or passive guidance which relies on emissions from the target itself. Hyperactive isn’t a standard term for this concept.
