摘　　要：针对Hough变换法计算量大、存储量大以及在参数空间量化间隔和积累方式难于选取的问题,提出一种改进的Hough变换法,避免了参数空间间隔的选取问题。密集杂波背景下多目标的航迹起始仿真实验表明,该方法能大大改善航迹起始的正确性和反应时间,有效改善局部峰值簇拥现象,而且对杂波干扰具有更好的稳健性,比较适合于密集杂波下目标的航迹起始。Aiming at the problem that the Hough transform method needs a lot of calculation and storage,and it is hard to select the quantization interval and accumulation mode in parameter space, this paper puts forward a modified Hough transform method, which can avoid the selecting problem of the parameter space interval. Track initiation simulation experiment of multi-target under the background of dense clutter shows that the method can improve the validity of track initiation and reduce the response time greatly, effectively improve the phenomenon of part peak gathering, and has better stability to the clutter jamming, is more suitable for target track initiation under the surroundings of intensive clutter.
