What functions are allowed by the hardware and software component of the AIM-120 guidance section?

The hardware and software components of the AIM-120 guidance section are designed to perform several critical functions necessary for the missile's operation and effectiveness. The correct choice highlights the key roles of acquisition, tracking, navigation, data link processing, and secondary power.

Acquisition is the process by which the missile identifies and locks onto its target. This is crucial for ensuring that the missile can effectively engage the intended target. Tracking involves monitoring the target's position in real-time to adjust the missile's course accordingly. Navigation is vital for guiding the missile through its flight path, ensuring that it arrives at the target location accurately.

Data link processing allows for communication between the missile and the launch platform or command units. This enables updates and adjustments to be made to the missile's trajectory based on real-time information. Secondary power is essential for operating the guidance section's onboard systems, ensuring they have a reliable power source throughout the flight.

Other options mention functions such as targeting, propagation, or scanning, but these do not encompass the comprehensive range of activities handled by the AIM-120 guidance section as effectively as the correct answer.
