The component of primary radar responsible for generating signals is the transmitter. The transmitter sends out radio frequency signals that are emitted into the atmosphere. These signals travel until they encounter an object, such as an aircraft, and are then reflected back toward the radar system. This process is crucial for detecting and tracking objects in the airspace.

The role of the transmitter is foundational to the entire radar operation, as it initiates the detection process by creating the signals that are necessary for identifying the presence of objects. The antenna functions in directing these signals and receiving the echoes, while the receiver processes the reflected signals. The display is used to present the information visually to air traffic controllers. Understanding the function of the transmitter is key in grasping how radar systems efficiently operate to maintain safety in air traffic control.
