How many targets can be tracked simultaneously by the AN/MPQ-64 Sentinel?

The AN/MPQ-64 Sentinel is an advanced multi-function radar system used primarily for air defense and battlefield surveillance. Its capability to track multiple targets is a key feature that enables effective threat detection and management. The correct answer indicates that the Sentinel can track up to 50 targets simultaneously. This capability is essential for managing various threat types in complex operational environments, allowing for a greater flexibility in air defense operations.

Having the ability to monitor numerous targets enhances situational awareness for military personnel, as they can respond to emerging threats effectively while providing comprehensive coverage.

The other choices reflect target tracking capabilities that either fall short or are unrealistic for the system's specifications, given the advanced technology integrated into the AN/MPQ-64 Sentinel. This radar was specifically designed to handle a significant number of targets to maintain efficiency in operations, and its design supports this specific target tracking capacity of 50. Thus, understanding the operational capacity of the system helps in recognizing its value in air defense strategy.
