Abstract :
A wide beam, forward looking, FM sonar using a purely audio information display, derived from twin receiving arrays, is described. The system was developed with the aim of providing an effective, but inexpensive, sonar for fishfinding. Preliminary sea trials with this system have indicated that accurate target tracking may be achieved without scanning of the transducers, and that the detection capability of the system, is considerable.
