Study on three dimension assignment algorithm of radar and ESM data association

Among various data association algorithms, the Lagrangian relaxation algorithm of the assignment problem has an advantage in satisfying the association accuracy in application while the calculating speed of this algorithm is not satisfied. This paper presents some studies of the elements that affects the data association of multisensor-multitarget in Lagrangian relaxation algorithm. The effect of data association can be improved through rational modification of the elements involved. Simulation results are given to illustrate the effectiveness of the proposed modification algorithm in this paper.
