Which capability allows the Avenger system to effectively track airborne targets?

The ability of the Avenger system to effectively track airborne targets is primarily due to its advanced onboard radar systems. These radar systems are designed to detect and track various aerial threats in real time, even in challenging conditions. Advanced radar technology allows the Avenger to distinguish between different types of targets, assess their speed and trajectory, and maintain a continuous tracking capability. This ensures that the system can respond accurately to incoming targets, which is crucial for effective air defense.

The other options, while they may represent aspects of military operations or the functionality of missile systems, do not directly address the core capability of tracking airborne targets. For instance, moving targets continuously might describe a dynamic operational scenario, but without the robust radar systems, tracking would be significantly hampered. Similarly, adjusting course based on interception angles and employing multiple missile types may enhance engagement strategies, but they rely heavily on the initial tracking provided by the radar systems.
