Abstract:
This paper presents a data reduction algorithm to
increase the efficiency of radar simulation. The features of artificial and
natural shoreline data are analyzed on the basis of original shoreline data,
and the characteristic points of shoreline data are extracted on the whole
by identifying the direction and curvature of the vector shorelines and
using the topology controlling algorithm. Characteristic points of shoreline
data are also extracted locally using an optimization algorithm of area loss
ratio control. Therefore, all data points that represent shoreline features
are extracted as the reduction result. Theoretical analysis of the results
indicates that the proposed algorithm has a high data reduction rate.
Moreover, the reduced data retains the shoreline's geometric features and
fits well with the shoreline. Further, the accuracy analysis results show
that the geometric accuracy of the algorithm is sufficiently precise for
radar simulation.
Keywords: Data reduction algorithm, data statistics, curve identification, topology controlling, radar simulation
