Which type of tracking refers to when the weapon sends out tracking energy?

The type of tracking that refers to a weapon sending out tracking energy is known as active tracking. In active tracking systems, the weapon emits its own signal or energy, such as radar waves or laser beams, which then reflects off the target and returns to the weapon system. This allows the weapon to continuously track the target's position and adjust its trajectory accordingly.

Active tracking systems are advantageous because they can effectively operate in environments where the target may be moving or changing its position. The emitted energy provides real-time feedback, enabling the weapon to make precise adjustments as needed. This level of control improves accuracy, especially in dynamic combat situations.

In contrast, semi-active and passive tracking systems rely on external sources of energy or signals that are not generated by the weapon itself. Semi-active tracking requires a third-party illuminator or source to provide the signal for guidance, while passive tracking systems rely on detecting the energy emitted by the target without any active emissions from the weapon. While these systems have their own use cases, they do not provide the same level of active engagement as active tracking does. Control, while related to guiding a weapon, does not specifically refer to the emission of tracking energy.
