If direction of horn-signal can be detected, it would be very useful for the safety navigation. The signal which was generated by a ship (Horn-ship) was picked by three microphones placed on the compass deck of another ship (Measurement ship). A series of experiments were carried out for various distance between two ships in the range from 600 to 2000m. In this system, the signal was digitalized with an A/D converter and sent to the microcomputer, and the direction was detected using these data. The error was less than ±15[deg], but the direction could not be detected, when SPL (sound pressure level) of horn-signal was about 50dB.
