The radar transmitter is responsible for generating and emitting the radio frequency signals that radar systems use to detect objects. It converts electrical signals into electromagnetic waves and sends them through the radar antenna. The power output of the transmitter plays a significant role in the range and effectiveness of the radar system. High-powered transmitters enable long-range detection and improved resolution, which is essential for applications like weather radar, air traffic control, and military surveillance. The transmitter must be finely tuned for optimal performance in specific radar applications.
