摘要
Hough变换是一种用于雷达长时间积累的有效方法,提出一种改进的Hough变换方法。与传统的方法不同,新方法把数据空间中的点映射到由斜率和截距定义的参数空间中,并通过对同一时刻到来的所有数据进行整体平移,实现对数据的映射。该方法降低了Hough变换的计算量。理论分析和仿真试验验证了新方法的有效性。
In this paper, a new algorithm is proposed for radar detection based on Hough transform. Unlike the traditional method, the idea of the proposed scheme is that the points in data space can be mapped into the Hough parameter space of slope and intercept. The parameter cells can be shifted to implement this transform. Therefore, the computation burden is reduced. In addition, the false alarm probability and detection probability are also investigated. And then its efficiency is shown with some simulations. Finally, the reduction of computation is illuminated in details.
