What is the formula for the closing speed of a moving RADAR front antenna?

The formula for the closing speed of a moving RADAR front antenna is defined as the sum of the speeds at which the patrol vehicle and another object are approaching each other. When determining the total speed of the two moving entities in the context of radar measurements, the correct approach is to identify how fast they are reducing the distance between them.

In this situation, the separation speed indicates how quickly the two objects are moving apart, while the patrol speed represents the speed of the vehicle monitoring the other object. By subtracting the patrol speed from the closing speed, we effectively extract the component of the closing speed that is attributable solely to the other moving object. This gives us a clear understanding of how quickly the radar is registering the approach of the target, leading to the straight-forward computation needed when employing radar technology to assess speed and distance.

The option that mentions the relationship correctly captures this dynamic, emphasizing the need to closely analyze the relative motion of the entities involved for accurate data collection.
