What does the hovering (helo) helicopter exclusion function prevent?

The hovering helicopter exclusion function is specifically designed to prevent the detection of hovering helicopters and other similar targets. This function is particularly important in air defense systems because hovering helicopters can often be friendlies operating in sensitive environments, such as in urban areas or near friendly ground troops. By excluding these targets from detection algorithms, the system can reduce potential false alarms and improve the overall effectiveness of the air defense network.

The focus on hovering helicopters allows the system to distinguish between various types of aerial targets that may not pose a threat, thereby streamlining the operational response and ensuring that resources are concentrated on actual threats. In scenarios where hovering craft are common, being able to filter them helps prevent unnecessary engagement or misidentification, which is crucial for maintaining situational awareness and operational integrity.
