Abstract Radar usually needs to detect targets under the dense pulse jamming condition, and the target information mixes up the fragmentary plots of false target jamming after it has been jammed by those pulses. It is difficult for the existing methods to initiate tracks effectively under the false target jamming condition. A track initiation algorithm based on the traditional randomized Hough transformation is proposed. The technology of sequence check is adopted to design the rule of sampling termination. Moreover, the parameter set of a flight feature constraint projection is constructed to eliminate any false tracks. Simulation results show that the proposed algorithm provides an excellent practicability for an information synthesis system, its average ratio of false tracks is only 14.9%,and its computation time occupies 9.5416 seconds.
