| 摘要: |
| 设计了适合安装在汽车前保险杆的超声障碍检测系统。提出了一种新颖的混合型超声波换能器阵列、基于换能器阵列合成孔径和超声波脉冲编码的障碍检测算法，以区分回波信号是否含有危险信息。理论计算与实验结果表明，该系统可检测到直径15mm的平板目标，其有效测量距离为0.2～25m，并可实现多目标定位。 |

| Abstract: |
| An ultrasonic obstacle detection system for mounting on the front bumper of an automobile was designed. Using an omnibus ultrasonic transducer array and ultrasonic pulse coding techniques, an algorithm for collision identification was formulated based on a synthetic aperture to discriminate between echoes constituting real threats and those that do not. Theoretical calculation and test results show that the detectable diameter of flat boards is 15mm, and the active range is between 0.2～25m. Furthermore, the multiple obstacles in front of the automobile can be located simultaneously. |
