Title: Underwater transmitter/receiver using identification symbol
Inventor: TAKARA SHIYOUICHI
IPC: G01S7/536
Filed: 1979-02-10
Abstract: PURPOSE:To eliminate the interference of an underwater transmitter/receiver by applying binary signals having no correlation to each other to the transmitter and the receiver, transmitting sound waves modulated by the signals, and selecting upon receiving of the signals only the sound wave matching the self symbol. CONSTITUTION:An underwater transmitter first transmits from its symbol genertor 9 binary signals having displaced phase of self correlation, that is, maximum when the time delay is zero and lower when the phase is displaced with low correlation between the symbols such as, for example, M series symbols having no correlation to each other and transmits them from a transceiver 1 through a symbol modulator 7 or the like under water. Then, a transceiver 1 receives the signal and applies it through a receiving amplifier 2 or the like as an electric signal converted from the signal into a symbol detector 4. The detector 4 detects the signal received by the correlation method whether it is self symbol or not and simultaneously measures the phase difference and amplitude of the signal to thus indicate the distance to a target to be reflected and the reflecting intensity on an indicator 5. Since it only detects the symbol applied to itself, no interference occurs thereat.
