Implementation of ranging system using ultrasonic sensor and microcontroller unit for aviation industries

In the aviation industry, radio detection and ranging is employed to evaluate the height, distance, bearing, size, trajectory or velocity of both dynamic and static objects. Ultrasonic waves can also be used instead of electromagnetic waves in ultrasonic sensor. This research paper presents the real time implementation of a less-expensive ultrasonic detection and ranging system built based on Arduino Uno 328 microcontroller. It utilizes ultrasonic sensors attached to a servo motor which rotates from 00 to 3600 to detect an object in range within 400cm which passes the data to an Arduino microcontroller, this then gives visual representation on the software called Processing-3.5.4 software (Processing development Environment) java language. The Processing displays on an LED (Light Emitting Diode) screen graphical information such as bearing, size, range and position of the object depends on the proximity of the object to the ranging system. Result obtained shows a maximum a good maximum error of 7 % for the test object considered. Hence, this system can be deployed in the field.
