An algorithm of maneuvering target tracking with IRSTS based on infrared radiation information of double bands

By using the infrared radiation information of the target located by double bands IRSTS,the pseudo-range information of the target was deduced to cause double bands-IRSTs in single observer to be observable.Furthermore,the pseudo-measurement equation was given and a modified current statistical model(CS) and UKF with the minimal skew simplex sampling strategy was applied.Based on them,an algorithm of maneuvering target tracking with IRSTS was presented on the basis of infrared radiation information of double bands.The theoretical analysis and simulation results show that the algorithm can effectively track maneuvering target and be widely applied in practice.
