The Angular (cosine) effect plays a significant role in how radar measures speed and distance. In stationary radar mode, the radar unit is typically fixed in one place and measures the speed of moving objects relative to its beam path. The angular effect comes into play due to the way radar waves interact with the target.

When a target moves toward or away from the radar at an angle other than directly in line with the radar beam, the measured speed can differ from the actual speed of the target. The cosine effect accounts for this angular discrepancy by adjusting the speed reading based on the angle of approach or departure relative to the radar's line of sight.

In stationary radar deployments, this means that when calculating the speed of an oncoming vehicle, the unit effectively compensates for the angle at which the vehicle is traveling. This results in more accurate speed readings, which is critical for law enforcement and traffic monitoring purposes.

In contrast, moving radar and other mobile units would not benefit as much from this angular correction because they are generally oriented parallel to the direction of travel, which mitigates the angular effect's influence on speed readings.
