Abstract:

Considering the four defects of construction and theory of IMMPDA algorithm which is proposed by Y. Bar Shalom and H. A. P. Blom, the authors work out a new Combined IMMPDA algorithm C IMMPDA algorithm. In C IMMPDA, a global optimal validating gate for every sub filter is constructed instead of the different gates for every sub filter in IMMPDA algorithm. That means it has only one PDAF in the filter system. All the formulas are deduced and the diagram of the new algorithm is drawn. The work makes the IMMPDA more satisfactory in construction and theory. Simulation results show that the new algorithm will decrease the computational burden and be of much better performance than IMMPDA.
