What is the function of a radar transmitter?

• A. To display radar data
• B. To emit radio waves that travel to the target
• C. To analyze incoming signals
• D. To power the radar system

Answer: (B)

The function of a radar transmitter is to emit radio waves that travel to the target. This is a crucial step in the radar system's operation, as the transmitter sends out coded electromagnetic waves, which then reflect off objects (the targets) in the environment. These reflected waves, or echoes, are critical for determining the presence, distance, speed, and size of the objects being monitored. Radar systems depend on this mechanism to gather data about the surrounding area, which is later processed to provide information about targets. The quality and characteristics of the emitted signals significantly affect the radar's range and accuracy. Other functions related to radar, such as displaying data, analyzing signals, or powering the system, do not involve the fundamental role of the transmitter in generating the initial radio waves necessary for target detection and measurement.
