Abstract: Aiming at the diculty of modeling and solution for information correlation (IC) of distributed passive sensor (DPS) information fusion (IF) systems, a model of 2-sensor IC based on a hybrid ordered delaminated information fusion structure is studied. In order to utilize the advantage of computational intelligence (CI) in solving parallel computing problem and combinatorial optimization problems, solutions to IC based on simulated annealing, genetic algorithm and neural network respectively are supposed. Taking neural network IC as an example, the simulation calculation is carried out and the results show that the supposed IC algorithms based on CI are effective. It is of great significance to solve the IC problem for DPS in method.
