What happens when the RADAR unit is moved in stationary mode?

When the RADAR unit is moved while in stationary mode, the speed can become inaccurately recorded due to the design and operational principles of radar technology. In stationary mode, the unit is calibrated to measure the speed of moving objects against a fixed position. If the unit is moved during this mode, it may not accurately account for the change in position, leading to incorrect speed readings. RADAR relies on the Doppler effect, which measures changes in frequency as objects move relative to the radar source. When the unit is shifted, the reference point for these measurements is altered, thus affecting the calculation of speed.

The other options do not accurately describe the impact of moving the radar in stationary mode. For instance, the RADAR reading is not maintained in the sense of remaining accurate, as the speed would no longer be valid. While a reset might occur, it’s dependent on the specific unit’s programming and functionality; it’s not a uniform response. Lastly, the notion that it cannot measure speed at all is misleading; it may still recording something, but that data would not be reliable due to the movement.
