Application of four-dimension assignment algorithm of data association in distributed passive-sensor system

Abstract

The disadvantage of multi-dimension assignment algorithm of data association in distributed passive-sensor system is the lower processing speed. The modified optimal assignment algorithm is presented in this paper. The new algorithm avoids a large quantity of calculation of cost function of 4-tuple measurements and removes the disturbance of some false location points. Simulation results show that by using the algorithm discussed in this paper, not only the calculation burden is reduced greatly but also the accuracy of data association is improved correspondingly. © Springer-Verlag Berlin Heidelberg 2005.
