The ControLaser performance does not degrade in the range of interest, 10-60 meters, during weather conditions caused by rain, snow, dust and fog, as long as the driver has visibility to the target. These performance will degrade with visibility mainly by fog. The degraded performance of the ControLaser are reported in the communication link. Targets Filtration, Detection and False Alarms Targets are detected even if they have low signal reflection in the defined beam of the ControLaser. The definition of the beam is very sharp in angles to avoid signals from road signs above the lane, signals from bridges and detection of targets in adjacent lanes on the highway.
False alarms are limited and avoided by software filtering.
It is nonreactive to interference originating on other vehicle's laser detector or any other laser device. Target is detected after a group of readings, in the range, is collected sequentially. A set of groups is called a legitimate target if the range of the groups is not changing too fast. Filtering out of occasional targets like trees, Bridges and road signs. Filtering out of targets that may be detected while driving in a curved road.
