Answering-measure radar for expressway automotive anti-collision system application

Based on the characteristic of closure management for expressway and the demand of low cost for economic car in China, a new automotive anti- collision managing model is proposed, which can be implemented by the supervisory and managerial department. A scheme for automotive anti-collision radar is given based on answering-measure, some critical performances of the radar have been analyzed and the measuring performance of radar is tested, according to the testing result, the radar realizes the function of measuring and automotive anti-collision in expressway.
