  • Estimating ship velocity through the water and over the ground
    Patent number: 6229761
    Abstract: A method and system are provided to estimate a ship's velocity. Two ship sonar returns from two different directions are selected. Each return includes volume reverberation data and bottom reverberation data. Doppler shift for each of the two returns based on the volume reverberation data is determined as a basis for estimating ship velocity relative to the water. Doppler shift for each of the two returns based on the bottom reverberation data is determined as a basis for estimating ship velocity relative to the ground.
