据统计,80%的车祸都是由于司机反应不及时所引起的,而其中65%以上属于追尾相撞,那么现存的世界各国所研制的几十种汽车防撞雷达为什么又没得到广泛应用呢?原因主要是体制问题,其次是成本问题.为此,提出了基于编码或码字识别汽车防撞雷达这一设想及其示例,即变初值变结构(VIVS)准混沌编码识别汽车防撞雷达方案的核心技术,并对可行性进行了分析与讨论.

It is reported that the 80% traffic accidents have been caused by the slow and insensitive reaction of drivers, in which more than 65% belong to the rear- end collision. Why have those automobile collision avoid and radars existing all over the world not been used extensively? The primary reason is that the mode is too simple, and the secondary reason is the high production cost. According to the reasons stated above, the automobile collision avoidance radar based on coded identifier is proposed, and an example is provided that is the critical technology of variable initial variable structure (VIVS) pseudo - chaos encoded identif-ying automobile collision avoidance radar. Finally, the feasibility of the radar is analysed and discussed.
