What is one method for ensuring accurate radar readings?

Maintaining a consistent operating distance from the target vehicle is a fundamental practice for ensuring accurate radar readings. When the radar is positioned at a stable distance, it minimizes potential errors caused by the Doppler effect and signal strength variations. This consistent distance allows for more reliable measurements, as the radar can effectively gauge the speed of the target without fluctuations that could arise from moving closer or farther away during the monitoring process.

In contrast, altering the angle at which the radar is aimed can introduce inaccuracies, as the radar's performance depends heavily on the alignment with the target's movement. Using the radar in different weather conditions might not yield the same accuracy, as elements such as rainfall, fog, or snow can obstruct the radar signal. Changing the radar settings frequently can lead to inconsistencies in the data collected, as each setting may perform differently under various circumstances, adding another layer of potential error to the readings.
