Hierarchical Fast Data Association in the Passive Sensor System
Zongxiang Liu · Dianzi xuebao · 2004
The key problem in the passive sensor system is the problem of data association.Multidimensional assignment algorithms have been shown to be very effective for data association,but multidimensional assignment is NP-hard problem and candidate assignment tree building consumes a lot of time.To solve the problem of fast data association in the passive sensor system,the paper presents a hierarchical fast association algorithm that reduces candidate association using statistic test and finds the correct association using hierarchical searching.Simulation results show that the algorithm is effective,and its correct association rate is higher than that of the lagrangian relaxation algorithm.
