What does "beamwidth" refer to in RADAR technology?

Beamwidth in RADAR technology specifically refers to the angle of the radar beam, which is crucial for understanding how radar systems focus their emitted signals and interpret the returning echoes. A narrower beamwidth allows for higher resolution and more precise targeting since the radar can better distinguish between closely spaced objects. Conversely, a wider beamwidth can cover a larger area but may result in less resolution, making it challenging to differentiate between targets.

This concept is significant in many applications, including air traffic control, weather observation, and military operations, where clarity and specificity are paramount. Different radar systems are designed with varying beamwidths to optimize them for their intended purposes, balancing coverage area against resolution capabilities.
