Locking the target vehicle's speed is the correct course of action when dealing with a potential selectivity problem because it provides a stable reference point for the speed of the target. This allows the operator to confirm that the speed reading is accurate and not influenced by any errors caused by possible overlapping signals from other vehicles or environmental factors.

By locking the speed, the operator effectively captures a momentary reading that can be analyzed without the influence of changes that might occur if the target were in motion or if there were interference from other vehicles in the road. This technique helps ensure the reliability of the data being collected.

In contrast, altering the RADAR settings, using a different RADAR unit, or adjusting the angle of the RADAR antenna could lead to further complications or inaccuracies, as these actions might change the detection parameters or introduce new variables that could affect readings. Therefore, focusing on locking the speed of the vehicle ensures you're working with the most reliable data.
