If the target speed does not change with patrol speed in same direction mode, what does this indicate?

When the target speed does not change with patrol speed in same direction mode, this indicates that the radar is functioning correctly for that specific operating mode. In same direction mode, the radar measures the speed of a target relative to the speed of the patrol vehicle. If both the patrol speed and target speed remain constant without any variation, it confirms that the radar has accurately locked onto the intended target and is processing the speeds as expected.

A properly set radar would register the target's speed relative to the patrol speed, thus if there is no change in the target speed while the patrol speed is consistent, it implies that the radar is effectively tracking the vehicle in the same direction. This demonstrates a fundamental principle of radar operation where the relative speeds should reflect proper functioning, reinforcing the notion that the user has selected the correct mode for the operation.
