Abstract
A collision avoidance system particularly suited for automotive applications includes an electro-optical rangefinder scanner, retroreflectors on target vehicles, and a processing unit. The rangefinder supplies data on the range and angle of target vehicles to the processor, which monitors each target vehicle's position, speed and acceleration and constantly determines and updates target range, angle, velocity, acceleration and predicted separation distances. A warning signal or evasive manuever instructions are issued if the predicted separation at the time of intercept is below a minimum acceptable value.
