A multisensor track-initiation algorithm is proposed. The algorithm ma
rries conventional gating approaches with log-likelihood-ratio test ba
sed data fusion methods and effectively deals with the missing measure
ment problem. The application of the proposed method to the low-elevat
ion track initiation problem using shipboard radar and infrared sensor
s is discussed. Simulation results are presented that compare the perf
ormance of the proposed algorithm with that of the AND algorithm.
