A Time Calibration Algorithm and Its Application in Marine Information Processing
Tianhao Tang · Navigation of China · 2010
Traditional time calibration algorithms in AIS and radar information fusion have shortcomings in computation cost and accuracy,besides,sampled information from AIS and Radar would probably be inaccurate or partly missing.Aiming at those problems,a time calibration algorithm based on Least-Square Criterion is presented.In the new algorithm sampled data by sensors are fitted by Spline function to get smooth curve for each,and the Spline function with minimal square sum of fitting error in the set of curves is taken as the resultant function.Against traditional cluster algorithm,effectiveness of the new algorithm is validated by computer simulation with Matlab.
