Filed: 1990-01-08
Abstract: PURPOSE:To discriminate a target signal from a sailing sound and a wave plowing sound, etc., and to early classify the target sound by a video by classifying a passive reception signal by color for every frequency band and performing color display. CONSTITUTION:The frequency band of the passive reception signal 10 is divided by band pass filters(BPF) 1-4 in a narrow band and the respective band outputs are classified by color to be displayed by a display part 5. With such constitution, the peaks in the bands of the sailing sound of one's own vessel 6A and the target sound 7A are deviated in the frequency distribution of the signal 10. When the peak of the sailing sound 6A is nearly at frequencies f1-f2 and the peak of the target sound 7A is nearly at frequencies f4-f5, the signal of the sound 6A and the signal of the sound 7A are transmitted to the display part 5 through a BPF 1 and a BPF 4 respectively. Therefore, the display 6 of the sailing sound of one's own vessel and the display 7 of the target sound are superposed to be displayed between the starting position 8 and the branching position 9 of the target sound on the display screen of the display part 5. However, the target sound is discriminated and displayed clearly by performing the color display of the BPFs 1 and 4 in blue and red respectively.
