Improved Distance Measurement Using Ultrasonic Sensors

The paper presents a system based on an ultrasonic emitter and two ultrasonic receivers which can locate more precise an object located in their detection range, being able to measure the distance to the object and the angle in respect with the front perpendicular direction. The sensors are read by a Lab View virtual instrument that drives the emitter and collect the echoes and based on geometrical equation computes the two parameters. The system architecture, the software application and some preliminary results will be presented in the paper.
