A fan beam scan Laser Radar has been developed for a Radar Brake System. The Radar has a wide scan area such as 350 mrad of the horizontal scan angle and 50 mrad of the vertical spread angle, and has a narrow detection resolution, of 0.1 m. Distance data is generated 640 times per 0.1 s. But this data includes noise information for example, roadside reflection, next lane-car reflection, etc. And so the authors had to eliminate it and extract the target information important for vehicle control. This target information is acquired by 'Two-step labeling process.' First, distance data from one scan is categorized into small block range of distance, and some small block data is generated as 'Block Labels'. This process is named 'Block Labeling'. Second, these 'Bock Labels' are categorized by relative velocities and distances, and some big group data is generated as 'Groupe Labels', which may indicate a vehicle and/or obstacle. This process is named 'Group Labeling'. Utilizing these processes coupled with a high performance hardware, we have realized a Laser Radar system applicable for vehicle control.
