Track initiation is a precondition to carry out tracking targets effectively. In the paper, an algorithm of track initiation based on clustering and Logic - Basic approach is proposed. First., the data transmitted to the fusion center are clustered, which makes the data in each cluster stand for the same target. Then the center of each cluster is found and taken as the measurement from single radar. By doing so, the track initiation process is simplified. According to the characteristic of targets' movement, an improvement is made in the Logic-Basic approach. Simulation results indicate that the algorithm is effective.
