Abstract

When several targets have been detected by radar in the same wave gate, their measurement errors are correlated significantly. In this study, the discussed approaches registers the sensor bias and correct the radar measurement error of non-cooperation target by utilizing the high precision GPS measurements of the coexistent target and the strong correlation assumption among the radar measurements. The simulation results show that the precision of the target state estimation based on the bias compensation and the error correction in this study is significantly improved.
