Using a RADAR in an incorrect mode affects how much the target speed display changes in relation to patrol vehicle acceleration?
It does not change
It changes by 1 mph
It changes by 2 mph for each mph change
It changes by 3 mph
The correct answer is: It changes by 2 mph for each mph change
Using a RADAR device in an incorrect mode can significantly impact the accuracy of the target speed display in relation to the patrol vehicle's own acceleration. When RADAR is configured improperly, it often results in a situation where the RADAR reading accounts for the relative motion between the patrol vehicle and the target, leading to a multiplication of the speed error. In this case, the correct answer indicates that the speed displayed by the RADAR changes by 2 mph for each 1 mph change in the actual speed of the target. This means that the RADAR picks up not only the speed of the target but also incorporates the patrol vehicle’s acceleration into the reading, effectively doubling the expected speed change. This understanding is crucial for law enforcement personnel using RADAR technology, as it highlights the importance of using the device in the correct mode to ensure accurate speed readings. Improper configuration can lead to misinterpretations of the target's speed, potentially undermining the reliability of speed enforcement actions taken based on those readings.
