表示装置。 A transmitter as an underwater mobile body that transmits ultrasonic pulses from underwater; a receiver that receives signals from the transmitter; and a receiver that performs necessary signal processing on the output signal from the receiver; Recording of direct wave signals propagating directly from the transmitter to the receiver and reflected wave signals guided to the receiver via the water bottom over time based on the output signal of the receiver. In the recording and display device for an acoustic positioning device, the receiver includes: a time difference detection circuit that detects a reception time difference between a direct wave signal and a reflected wave signal; and a time difference detection circuit that detects a reception time difference between a direct wave signal and a reflected wave signal; a depth difference conversion circuit that converts into a signal representing a depth difference with the water bottom; a recording reference position of a constant depth is set in correspondence with the direct wave signal, and the reflected wave is changed by the depth difference with respect to the recording reference position; 1. A recording/displaying device for an acoustic positioning device, comprising: a recording signal generating circuit that generates a depth difference recording signal corresponding to a signal of the depth difference recording signal and applies the depth difference recording signal to a recording device.
