Abstract
Based on the analysis of the measurement characteristics and uncertainty of ultrasonic sensor
a novel ultrasonic sensor model is introduced.In this model
the reliability of grid information in the sector region of ultrasonic sensor can be calculated using the D-S evidence theory
the obstacle position can be detected in the range of ultrasonic sensor.The simulation results indicate that the model is efficiency and applicability.
