| 摘 要： | 高速公路汽车防撞是一个具有重要意义的研究课题，而车距测量又是防撞技术的关键．本文提出一种新的同步被动式测距法，这种方法具有波束行程短、传播衰减小和抗假目标能力强等优点，以超声波作为测距波束即可满足测量车距的要求。

| Abstract: | Automobile collision avoidance on expressways is an important subject of research, and the ranging bettween automobiles is a key technique. This paper proposes a new synchronous passivity ranging method which has many advantages such as short beam route, less transmitting attenuation and high correct recognition of spurious objects. This method can meet the demand for ranging between automobiles with ultrasonic wave beam. |
