What are the main components of a typical RADAR system?

A typical RADAR system comprises several essential components that work together to detect and locate objects. The primary components include the transmitter, receiver, antenna, and signal processor.

The transmitter generates electromagnetic waves, which are then emitted by the antenna. These waves travel through the environment and reflect off objects, returning to the system. The receiver collects these reflected signals, and the signal processor analyzes them to extract information about the object's distance, speed, and direction. This integration of components allows RADAR to effectively detect and track objects in various conditions, making it a crucial technology in fields such as aviation, meteorology, and maritime navigation.

Other options do not align with the fundamental architecture of RADAR systems. For example, cameras and lenses are components of imaging systems, not RADAR. Similarly, microphones and speakers relate to audio systems, while relays and controllers pertain to electronic control systems, making them unsuitable in the context of RADAR.
