What are the three types of beams used for scanning aircraft?

The correct answer is based on the fundamental operations of radar systems used in air defense. The three types of beams that are crucial for effective scanning of aircraft are search, verify, and track.

Search beams are employed to detect and locate potential targets within a region of interest. They allow air defense systems to scan the airspace broadly, identifying any aircraft that may pose a threat.

Verify beams are utilized for confirming the identity of the detected targets. This involves gathering additional information to validate whether the target is friendly or hostile, which is essential for making informed decisions in combat scenarios.

Track beams, on the other hand, are focused on monitoring the movement of identified aircraft over time. This continuous observation enables air defense systems to maintain accurate situational awareness and coordinate response actions effectively.

Understanding these functions is crucial for personnel operating within air defense systems, as it relates directly to their ability to manage and respond to airborne threats.
