Simulation Research on Radar-ESM Track Correlation
Zhang Xin-hua · Acta Simulata Systematica Sinica · 2002
The problem of radar-ESM correlation can be considered as a pattern recognition problem. The position of target can be ascertained by using the azimuth of target. Based on statistical hypothesis theory and fuzzy synthetic analysis, multi-threshold mathematical model, multi-target motion model and sequence time correlation mathematical model are presented in the paper. Furthermore, a fast correlation model based on accumulative data accounting is proposed by which the measurements of two kinds of sensors can be smoothed and interpolated on-line. The result of fast correlation can meet precision demand in track-to-track fusion. Finally, the simulations of correlation result on different movement situation are analyzed in detail. The analytical results have important reference value to practical application.
