The identity recognition of orbital cluster targets is the premise of fusing the detection information of each sensor.Normally,the detection information of cluster targets comes from radar,infrared and other heterogeneous sensors.Aiming at the problem of identity recognition of heterogeneous sensors in the case of target mismatch is analyzed,and the motion characteristics of the orbital target in the 2D angle plane of the infrared sensor,and proposes a method of multi frame identity recognition for heterogeneous sensors based on Hough transform is proposed.The simulation results show that the matching accuracy of heterogeneous sensor in target mismatch is improved effectively.
