A Tracking and Classification algorithm for Maneuvering Targets with Labeled Multi-Bernoulli
A tracking and classification algorithm for targets with labeled multi-Bernoulli(LMB)is proposed to solve the problem that the performance of existing tracking algorithms for multiple maneuvering targets seriously degrades under dense clutter environment. Firstly
target state is extended by introducing category information. Secondly
the transfer density of the target maneuver model is modified using attributes of the target class. The impact of a wrong maneuver model on the target state prediction is suppressed
and the new state transition density function is derived. In addition
a joint likelihood function for the attributes and position of the target is established to increase the discrimination between target and clutters
and the clutter suppression ability is enhanced. Finally
an improved prediction and update equation are derived based on the multiple model labeled multi-Bernoulli filter framework. Simulation results show that the proposed method still trackes multiple maneuvering targets even in a high clutter environment. The estimation error for the number of targets and the optimal subpattern assignment distance of the proposed method are 1/2 and 1/4 respectively
of those from the multiple model probability hypothesis density joint detection
tracking and classification(JDTC)filter
and 3/4 and 1/2
ksptctialy
of those from the multiple model cardinality balanced multi-target multi-Bernoulli JDTC filter.
