What is the name of the main beam of the antenna in radar technology?

The main beam of the antenna in radar technology is referred to as the boresight. Boresight is the direction in which the antenna is most sensitive and exhibits the greatest gain. This is crucial for radar systems as it indicates the primary direction in which the radar will transmit and receive signals. Essentially, the boresight aligns with the intended target area, allowing for optimal performance when detecting and tracking objects.

Understanding the role of the boresight helps in grasping how radar systems function. It enables effective targeting and maximizes the radar’s ability to receive reflected signals from targets within that beam. The other terms listed—control beam, azimuth angle, and antenna pattern median—serve different purposes in radar technology but do not specifically identify the main beam itself. The control beam often relates to adjustments in radar systems, the azimuth angle indicates the direction of the main beam in horizontal plane measurements, and the antenna pattern median refers to a measurement of the antenna’s radiation pattern but not the beam itself.
