DIGITAL SIGNAL PROCESSING SYSTEM OF ULTRASONIC SONAR

This article discusses an approach to the development of robotic sensory systems based on ultrasonic sensors and virtual instrumentation technology. Development is performed with the NI LabVIEW. The authors provide recommendations for the development of the sensor system configuration, data processing and visualization. The effectiveness of an ultrasonic sensor Maxbotix LV-MaxSonar-EZ3 has been evaluated. A method of error correction using digital signal processing system and additional IR sensor has been proposed.
