Description

Horn-signal is very important information. If the direction of signal-source can be detected by the horn-signal generated from other ship, it would be very useful for the safety navigation. This paper describes the system detecting the signal direction automatically. In this system, we consider a series of process of the sound sampling, data processing, direction detecting, as a sequential operation and examine algorithm which can quickly perform these processing by a personal computer. As a result, the detection takes time of 7 seconds each.
