| Abstract: | A vehicle guidance system has been developed using ultrasonic sensing. The ultrasonic technology is presented in this paper with reference to how it links in with the complete system. The ultrasonic unit is based on electrostatic transducer technology and comprises a separate linear array and curved divergent transmitter which gives it an effective field of view of 60° and a range of more than 5 m. The unit has been designed primarily for use on an unmanned vehicle travelling over rough, unknown terrain. |
