Abstract
This project exploits the graphic processing capability
of the Java language. The system described herein uses microwavebeacon
radar technology to locate an object and to display its position on a computer
terminal. The moving object is equipped with a small portable transmitter. Two
parabolic dish antennas triangulate on the exact location of the transmitter.
The incoming signal is processed to determine the direction of maximum power,
and the object's position is displayed on a screen. The
advantages of using high frequency microwaves are more precise detection and smaller
probabilities of signal jamming. Applications include the surveillance of laboratory
animals during experimentation and the possibility of one-way communication with
robots. The overall system consists of four main blocks: the transmitter, the
detection system, the motor control system, and the display system. By implementing
nonstationary antennas, the range of the system is doubled. The basic characteristics
of radar and the design equations for microwave communications are discussed.
Several conclusions based on the performance of the operational system and recommendations
for future work are also given. .
