When operating RADAR and a vehicle is moving towards you, how does the pitch change?

When operating RADAR and a vehicle is moving towards the operator, the pitch change is typically described as "up and high." This occurs because the RADAR system detects the frequency shift of the returned signal. As a vehicle approaches, the frequency of the reflected signal increases due to the Doppler effect, resulting in a higher pitch for the operator monitoring the signal.

This change in pitch is significant in speed detection, as it helps operators determine the speed of the approaching vehicle. The increase in frequency directly correlates with the vehicle's speed; thus, recognizing that the pitch goes up helps in accurately measuring and interpreting the vehicle's velocity.

Understanding this concept is crucial for speed detection operators, as it allows them to efficiently identify and respond to speeding vehicles based on the significant changes in pitch observed in the RADAR readings.
