How often should a radar unit be tested for accuracy?

A radar unit should be tested for accuracy at least once per year or following any major change to ensure that the readings it provides are reliable and accurate. Regular testing is crucial because it helps to identify any potential issues that may arise from normal wear and tear, environmental factors, or changes in equipment configuration.

Annual testing allows for preventative maintenance to be performed and ensures that the unit meets the operational standards required for effective radar use. Additionally, testing after any major changes—such as repairs, modifications, or significant alterations in the environment—serves to validate that these adjustments have not compromised the unit's accuracy. This practice is essential for maintaining the integrity of the data collected and ensuring compliance with regulatory standards.

While more frequent testing might seem beneficial, once a year provides a reasonable balance between maintaining accuracy and operational efficiency, thereby contributing to effective radar operation.
