| Abstract: | The classical fusion algorithm of multi sensors assumes that the measurement noises across the sensors are not correlated,but it is not true for some practical situation.The track fusion and measurement fusion techniques of multi sensor tracking system in case of correlated measurement noise are studied.Under the condition of correlated measurement noise,the improved algorithms of track fusion and measurement fusion in synchronized multi-sensor system are presented based on the linear unbiased minimum variance estimation theory.The algorithms presented are suited for the situation of both correlated measurement noise and irrelated measurement noise.Monte Carlo simulation shows that the algorithms presented in this paper improve the estimation accuracy evidently with low calculation load added when the measurement noises are correlated. |
| Keywords: | correlated measurement noise linear unbiased minimum variance estimation measurement fusion track to track fusion target tracking |
