Fusion Processing Method of Internal and External Torpedo Trajectories’ Data Based on Time Difference Weighting

Abstract

The torpedo trajectory data with high precision and high sampling frequency are needed for evaluating torpedo over-target situation and non-triggered fuze action function when torpedo sea trial results are evaluated. However, it is difficult to meet the evaluation requirements only by means of internal and external torpedo trajectory measurement data, and there is no applicable trajectory fusion method. In view of this, a fusion processing method of internal and external torpedo trajectories’ data based on the time difference weighting method was proposed, which combined the advantages of internal and external torpedo trajectories. The torpedo trajectory obtained by fusion has the advantages of high precision and high sampling frequency, which can fully meet the trajectory requirements for evaluating torpedo over-target situation and non-triggered fuze action function, and it has practical value in the torpedo trial field.
