Some characteristics of a new submarine mathematical model at the periscope depth

The effects of assuming a submarine model which does not accurately describe the dynamic system are presented in the paper. In the papers published so far submarine high-frequency disturbances are modelled by a simple afine form. The main disadvan-tage of such an approach is a poor correspondence with the real nature of submarine dynamics at the periscope depth. The modelling inaccuracies can result in biased estimates. Some results of the numerical analysis are also presented.
