Samenvatting
Various radar systems have been proposed as collision avoidance sensors for automatic braking and warning applications. Practical use of laser radar systems is near with the introduction of high power, high reliability laser diodes.Utilizing these new devices, a laser radar system has been adapted for measuring the distance to objects in its path. Test results show that the performance of laser radar is comparable to that of microwave radar.Considering the cost and size of the radar systems, laser radar would appear to be the more practical of the two.
