ESTIMATION
OF CURRENT COORDINATES OF ACCOMPANIED PATHS OF PILOTAGE IN COASTAL SEA REGIONS
A.I. Kravchenko
Possibility of
usage of the simplified dynamic filter – the αβ-filter for an estimation of
coordinates of the trajectory conductings of
sea-crafts is considered and analyzed. The expediency of usage of the given
modification of the dynamic filter, considering singularities of a path of
driving of a vessel in the form of segments of direct lines, small high-speed
parameters of driving and other singularities is argued. Parameters of
effectively length of a pulse response of the filter are defined. Formulas for
calculation of integral errors of estimations of coordinates of radar-tracking
marks are received.
Key words: handling, coordinates, marks,
vessels, filtration,
characteristic, radar-tracking signals, model.
