While LIDAR guns lock on to a certain point to obtain a single speed reading after multiple calculations they are effect by the cosine error, the Poliscan operates significantly differently to a conventional lidar gun in the sense it scans from side to side in a sweeping motion the amount of times per second this occurs varies depending on traffic density. The Poliscan does not lock onto a certain area of the car, but rather calculates the speed of a moving target multiple times based off positioning and vehicle width using intelligent software algorithms design by the manufacture. As a result, the Poliscan is not effect by the Cosine error.
