The invention discloses an adaptive distributed track data fusion method based on a covariance indicator function. The method comprises the following steps: 1) receiving and storing track data, and carrying out pretreatment on the received track data; 2) carrying out space-time registration on the multi-source track data; 3) associating the track data obtained by different sensors and determining correspondence relation between observation data and moving objects; and 4) carrying out fusion on the multi-source track data based on adaptive selection of fusion index, and determining motion state of each moving object. The method can selectively eliminate data having filtering divergence or overlarge system deviation and the like, which hinders improvement of precision of the fusion results, in the fusion process, and keeps the results having good consistency and carries out fusion.
