Abstract: A new algorithm based on grid clustering and logic method for tracking initiation (TI-GCL) was proposed to solve the problems of multiple false tracks and slow initiation in high-density clutter environment.In order to get more accurate clusters,the new algorithm uses the technology of grid cores-based and boundary optimization to deal with the echo points which come from high-density grid and low-density grid,then uses the similarity of data in each cluster to clustering,and ultimately utilizes the modified logic method to initial the object track.The simulation results show that the algorithm is capable of initiating tracks accurately and quickly in dense clutters environment,which can be used for practice of project.
