In Florida, traffic speed radar devices must be calibrated at least once a year. Additionally, they should be calibrated anytime they are repaired or after being involved in a significant event, such as a crash. Regular maintenance and calibration ensure the accuracy and reliability of the radar readings used in enforcement.
State police radar guns typically need to be calibrated regularly to ensure accurate speed readings. Calibration frequency can vary by state and department policies, but it's generally recommended to calibrate the devices at least once a month, or before any significant use, such as during traffic enforcement operations. Additionally, officers often perform a self-check before each shift to ensure the radar is functioning correctly. Regular maintenance and adherence to manufacturer guidelines are crucial for maintaining accuracy in speed measurements.

You can get radar detectors from Bestbuy.com and from Amazon.com. You should make certain that these devices are legal in the state you reside. In many places like Virginia they are illegal.
Radar guns used by law enforcement in Massachusetts must be calibrated at least once per year to ensure accuracy. However, some departments may require calibration more frequently based on their individual policies and usage.
airplane..bwahahahaha....
sonar devices map the sea floor, radar just boils water unless the signal is balanced ungodly.
The air traffic controller used radar to track the incoming airplanes.
Radar detectors are legal for passenger vehicles in North Carolina. However, they are prohibited for use in commercial vehicles. It is important to note that while radar detectors are legal, the use of radar jammers is illegal in North Carolina and throughout the United States. Radar detectors are devices that can detect radar signals emitted by police radar guns, while radar jammers are devices designed to interfere with or block radar signals.
Ground control, on initial contact.
The radar works just fine, but the operator (the traffic officer) may not be able to see an approaching vehicle as well or as far away in fog conditions. The proper way to use traffic radar is to observe a speeding vehicle, visually estimate its speed, and then confirm the speed with the traffic radar. In dense fog, the traffic radar may indicate speeding vehicles the officer cannot see.
None, they are legal!
