Abstract: Hough transform is widely used in track initiation, yet it performs worse with short-time-scanning. A fast track initiation approach based on the parallel Hough transform is proposed in this paper by changing the processing structure of Hough transform and the counter’s accumulating manner. After mapping the measurement sets of different time into the parameter space separately, the accumulated result corresponding to the measurement sets with the same index constitute an accumulated vector. Compare the nonzero element number of the vector with the predefined threshold. If greater, summation of the elements will work as the final results of the counter. And then make a decision whether to initiate the track or not through the threshold detection. Simulation results show that the proposed method can fast initiate the track accurately even under dense noise clutter environment.
