  • METHOD FOR CALCULATING FORWARD ACOUSTIC SCATTERING DOPPLER FREQUENCY SHIFT OF UNDERWATER MOVING TARGET UNDER IRREGULAR TRAJECTORY
    Publication number: 20240295652
    Abstract: The invention involves a method for calculating a forward acoustic scattering Doppler frequency shift of an underwater moving target under an irregular trajectory, comprising: (1) converting earth longitude and latitude coordinates of a transmitting end, a target trajectory, and a receiving end into rectangular coordinates, and sequentially marking the coordinates as (xS, yS), (xT, yT), and (xR, yR) (2) recording a target trajectory coordinate sequence as (xT(ti), yT(ti)), wherein i=1, 2, . . . , N, and calculating an average navigation speed ? within all time periods.
