Abstract:
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 electromagnetic 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 ultrasonic sensor, an Arduino
microcontroller, a servo motor and a java application for mapping the
electromagnetic waves. A prototype system is built by connecting the ultrasonic
sensors to the Arduino microcontroller’s digital input/output pins and
the servo motor also connected to the digital input/output pins. Both the
ultrasonic sensor and the servo motor are then clipped together so that as the
servo motor sweeps from right to left through an angle of 180 the servo will
rotate alongside it to capture any obstacle that moves in the radar range then
send the distance and angle information’s to the pc screen.
