What is the maximum angle that a stationary RADAR should be set up not to exceed?

The maximum angle at which a stationary radar should be set up, not to exceed, is 20 degrees for optimal performance. This angle is critical to ensure that the radar can accurately measure the speed of a target without experiencing significant multipath interference or range ambiguity. When the radar is positioned at a sharper angle, such as beyond 20 degrees, it increases the likelihood of detecting erroneous readings due to the changing Doppler effect as the angle affects the velocity component of the target relative to the radar.

Operating within this 20-degree threshold helps maintain the integrity of the radar signal and ensures consistent, reliable speed measurements, which is vital for enforcement and data collection purposes. Hence, adhering to this guideline supports not only accuracy but also adherence to protocols for law enforcement and safety.
