  • Method for producing at least information for track fusion and association for radar target tracking, and storage medium thereof
    Patent number: 9354305
    Abstract: A method for producing at least information for track association and fusion includes: collecting measurement values of targets for each sensing period; predicting state variables for the targets and error covariances for the state variables by using the collected measurement values and tracking the targets by using a reformed target tracking algorithm; transmitting track information including only data of the error covariance largest occupied among the error covariances to a fusion center; calculating similarity between the pre-stored fused track and the transmitted track information; sorting the track information by using the calculated similarity; and carrying out the track fusion based on the sorted track information.
    Type: Grant
