Which factor influences the maximum distance an object can be seen by speed measuring RADAR?

  1. The speed of the radar vehicle

  2. The sensitivity setting of the device

  3. The angle of the beam

  4. Weather conditions

The correct answer is: The sensitivity setting of the device

The maximum distance an object can be detected by speed measuring RADAR is significantly influenced by the sensitivity setting of the device. RADAR systems utilize sensitivity settings to determine how well they can detect and track objects at various distances. A higher sensitivity setting allows the RADAR to detect smaller objects or those further away, thereby increasing the effective range at which an object can be seen. Conversely, a lower sensitivity setting may limit detection capabilities, reducing the distance at which the RADAR can accurately pick up signals from vehicles. While factors like the speed of the radar vehicle, the angle of the beam, and weather conditions do play a role in overall RADAR performance, they are not as directly correlated to the maximum detection distance as the sensitivity setting. The device's configuration and technical specifications primarily dictate how well it can pick up signals, making sensitivity the crucial factor in determining the maximum distance for visibility.
