Project Overview

The objective for this project is to create a ultrasonic radar system capable of detecting multiple small objects. It should be able to accurately distingush between two objects in close proximity wether they are side-by-side or front-to-back. The system will use a set of eleven transducers with one receiver, and ten being transmitters. The transmitters will be placed into a linear phase array pattern. The use of a phase array will allow for a greater signal to noise ratio due to constructive interference, and will lead to a more narrow focused beam from better detection resolution. With the use of a phase array the radar can also scan all directions within its FOV, this is performed by changing the phase of the transmitters. The radar measures distances by determining the time delay of a pulse reflected by an object. The data for detected objects will be viewable through a 2D radar image display.
