[0027] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0028] The present invention is a kind of non-linear filter method for underwater navigation, purpose is to utilize the advantage of the filter method based on Bayesian estimation, provide a kind of cubic spline interpolation method of approaching the weak solution of navigation stochastic differential model in sections, thereby effectively It is ensured that it can better track the change of the system state, and the nonlinear filtering method of the present invention has high estimation accuracy, convergence speed and convergence smoothness.
[0029] Taking the underwater terrain-assisted navigation system as the background, the motion state of the submersible can be represented by a random process x(t), assuming that for time t∈[0,∞), all x(t) are defined in a fixed probability space ( Ω, F, P), where Ω is a non-empty set called a sample space whos...
