Embedded System Based Radio Detection and Ranging (RADAR) System Using Arduino and Ultra-Sonic Sensor

摘要

The applications of the radio detection and ranging (RADAR) systems in military installations as well as scientific and commercial facilities is powered by the ability of the RADAR systems to use electro-magnetic waves to determine the speed, range, altitude or direction of objects, either fixed or in motion. In the years since RADAR systems came into prominence, incalculable developments have occurred. Some of these are in the fields of navigation and positioning, target detection and tracking, energy optimization, and other applications. In this research, existing radar technologies are examined and an Arduino based RADAR system is proposed. The advantage of this is to drastically reduce power consumption and allow the designers to have access to a wide range of online communities of Arduino programmers and open source reusable code. The system consists of an ultra-sonic sensor, an Arduino micro-controller, a servo motor and a java application for mapping the electro-magnetic waves. A prototype system is built by connecting the ultra-sonic sensors to the Arduino micro-controller's digital input/output pins and the servo motor also connected to the digital input/output pins. Both the ulta-sonic sensor and the servo motor are then clipped together so that as the servo motor sweeps from right to left through an angle of 1800 the servo will rotate alongside it.
