Example of student work: final project presentation by Leon Fay, Miranda Ha, and Vinith Misra (a.k.a The Tunafish Team). This project will implement a phase-array sonar system that will create a two-dimensional map of the environment directly in front of the array and display it on a screen for the user. The system will consist of one acoustic transmitter and a number of receivers. The receivers will be placed in a linear array spaced appropriately. Analysis of the phase relationships (to determine the angle) and delays (to calculate distances) in the receivers will allow a two-dimensional map of the environment to be drawn.
