Fig. 6

The comparison of azimuth and distance RMSE at different standard deviations of distance, with CT model of turn rate 2.5°/s. There are two sub-figures (a) and (b) in this figure, in which, under the CT model of turn rate 2.5°/s., the changes of fusion RMSE of azimuth and distance are described along with different standard deviations of distance. The fusion RMSE in (a) and (b) is the mean of all results covering all fusion time steps
