摘要：In view of the inherent defects in current airport surface surveillance system, this paperproposes an asynchronous target-perceiving-event driven surface target surveillance schemebased on the geomagnetic sensor technology. Furthermore, a surface target tracking andprediction algorithm based on I-IMM is given, which is improved on the basis of IMMalgorithm in the following aspects: Weighted sum is performed on the mean of residual errorsand model probabilistic likelihood function is reconstructed, thus increasing the identificationof a true motion model; Fixed model transition probability is updated with model posteriorinformation, thus accelerating model switching as well as increasing the identification of amodel. In the period when a target is non-perceptible, prediction of target trajectories can beimplemented through the target motion model identified with I-IMM algorithm. Simulationresults indicate that I-IMM algorithm is more effective and advantageous in comparison withthe standard IMM algorithm.
