A Method of Maneuvering Target Tracking with IRSTS
IRST系统的单站机动目标跟踪算法研究

The infrared radiation power of the target received by IRSTS is introduced to target tracking for this bearings-only measurements system With the ratio of the two serial measurements of the infrared radiation power of the target, which eliminated the disadvantage of the uncertainty of the radiation intensity of the target,an IMM(interacting multiple model) algorithm is put forward. The performance of the algorithm is verified by simulating a highly maneuvering target tracking. The results show that when the measurement RMS error is small, it has little influence on the performance of the tracking in the whole trajectory of the tracking.The RMS position error of single coordinate axis is less than 7 m, furthermore,the most of it is less than 3 m; when the measurement RMS is large, the performance of the tracking is better at the near distance, where the RMS position error of single coordinate axis is less than 5 m, but it becomes worse rapidly at far distance.The largest RMS position error reaches 110 m. The RMS speed error has the similar results to the RMS position error.
