What does a distance test do to the unit in RADAR systems?

A distance test in RADAR systems calibrates the unit to ensure accurate distance measurements. Calibration involves adjusting and fine-tuning the system so that it can accurately interpret the time it takes for a radar signal to bounce back from an object, allowing for precise distance calculations.

When a RADAR unit is subjected to a distance test, it verifies that the return signal timing corresponds to known distances. This process is crucial, as any miscalibration can lead to incorrect distance readings, which may affect all subsequent measurements and interpretations of the data collected by the RADAR system. Regular calibration through distance tests is a standard practice to maintain the reliability and accuracy of RADAR operations.
