What is the crucial step to take when using moving RADAR tracking history?

The crucial step when using moving RADAR tracking history is to make a visual estimate of target speed. This step is essential because visual estimation helps the operator confirm the accuracy of the RADAR reading. By gauging the speed of the target visually, the operator can cross-reference the RADAR data, ensuring that the system's display reflects the true speed of the vehicle being monitored.

In practice, target speed estimation enhances situational awareness and assists in identifying potential inconsistencies between perceived motion and RADAR output. This is particularly important in real-world scenarios where various factors can affect RADAR readings, such as the presence of other vehicles, reflections, or environmental interferences.

While verifying environmental conditions, using RADAR in stationary mode, or adjusting the patrol vehicle speed are relevant aspects of radar operation, they do not directly address the need for immediate accuracy checks on target speeds in moving radar tracking history. Instead, the visual estimate serves as an immediate and practical approach to validate the findings of the RADAR system before taking further action.
