  • Underwater detection device, underwater detection method, and underwater detection program
    Patent number: 11280891
    Abstract: An underwater detection device may include a transmitter, which may include a transmitter, a receiver, and processing circuitry. The transmitter may be configured to transmit a transmission wave. The receiver may be configured to receive a reflection wave of the transmission wave. The processing circuitry may be configured to acquire a first position of a ship and a first measurement value that is a measurement result of the reflection wave at the first position, determine whether a relationship between the first position and a second position of the ship or another ship meets a given condition, and calculate a correction value based on the first measurement value and a second measurement value that is a measurement result of the reflection wave at the second position under a circumstance when the given condition is met.
