PURPOSE:To change easily a depth, towing a towing body, by using a depth control flag, and an acoustic transmitter and receiver, and a device for executing a signal processing basing on it and driving the flap, for a submarine towing body towed by a mother ship. CONSTITUTION:An acoustic signal processing device 24 executes a signal processing received by a transmitter and receiver 23. An output signal of the transmitter and receiver 23 is inputted to the first controlling circuit 41 through an input/output transformer 39 and a pre-amplifier 40. That which is related to a transmission in said signal is inputted to the second controlling circuit 42. That which is related to a set depth value in an output of this circuit 41 is inputted to a D/A converter 43, sent to a flag driving device 25 through a controlling circuit 44, and a control of a scrap 20 is executed. Also, a servo-amplifier 51 is controlled by a potentiometer 59. Moreover, a depth is measured by a water pressure detector 60 placed on the outside face. This depth is transmitted continuously to a mother ship and the depth is monitored. |
