Claim 5:
6. The fusion system of claim 1, wherein said preliminary GMTI tracks are represented by a 4 dimensional state vector (xtr(t), ytr(t), vx(t), vy(t)), where xtr(t) and ytr (t) are coordinates of the target track on x and y axes correspondingly, and where vx(t) and vy(t) are the velocity vector projections on the x and y axes, correspondingly, and wherein said preliminary GMTI tracks are associated with a corresponding covariance matrix, which is a 4×4 matrix:, (
