Abstract

Abstract:

Aimed at the problem of the window length chosen in the time registration algorithm based on curve fitting, an adaptive window length chosen algorithm based on the mode of the movement of a target is proposed. The movement of the target is divided into like-linear mode and curvilinear mode, and the slope of the trace of the target at each data point is calculated, so the state breaking point and the mode of movement at the point of time registration can be confirmed and the length of the window is chosen adaptively. Large numbers of simulations show the reliability of this algorithm under the condition of time delay and the maneuvering target.

Key words: time registration, curve fitting, data fusion, multi-sensor
