What is referred to as the area directly above the radar antenna?

The area directly above the radar antenna is referred to as the blind zone. This term is significant in air traffic control and radar operations because it describes the region immediately above the radar beam where no targets can be detected. The design of radar systems typically features a narrow beam projection, and as a result, there is a vertical distance right above the antenna where the radar cannot receive any signals. This blind zone can impact air traffic control operations, particularly when aircraft are climbing or descending, as their positions may not be tracked accurately until they exit this zone. Understanding the blind zone is crucial for air traffic controllers when assessing radar coverage and ensuring safety in the controlled airspace, particularly near airports where aircraft operate closely to radar installations. The other terms refer to different aspects of radar operation but do not accurately describe the area directly above the radar antenna. For instance, the search zone pertains to the broader area that the radar scans, while the detection zone refers to the space where radar can successfully identify targets. Tracking area generally denotes the region where radar can maintain a continuous track of a targeted object after it has been detected.
