Audio Sonar for Gaining Hands-On Experience of Radar Principles

While learning the theory underlying radar is important, it is also necessary to gain hands-on experience to truly understand the relevant concepts. However, radar systems are expensive and often perform important functions making it unlikely that students will be able to experiment with them. Furthermore, large spaces and expensive hardware are required as a result of eclipsing in pulsed radars. An audio sonar will be demonstrated to show how important concepts such as ambiguities, clutter, and others can be illustrated using a simple, low-cost audio sonar.
