一种基于Hough变换的航迹起始方法

雷达常用的航迹起始方式有逻辑法,直观法等方式。文章采取一种基于Hough变换的航迹起始方式,将经典Hough变换与修正的Hough变换进行对比,分析性能。Hough变换法主要应用于图像中的直线检测。由于目标在起始时其运动轨迹基本为一条直线,因此可以使用Hough变换法进行起始。但由于经典Hough变换要求较长的扫描周期且运算量巨大,因此提出了在三个扫描周期内采用修正的Hough变换法进行航迹起始。此方法大大提升了目标航迹起始速度。

The commonly used track initiation methods for radar are logic method,intuitive method,and so on.In this paper,a track initiation method based on Hough transform is used to compare the classical Hough transform with the modified Hough transform to analyze the performance.The Hough transform method is mainly applied to line detection in images.Since the target’s motion trajectory is basically a straight line at the beginning,it can be initiated using the Hough transform method.However,since the classical Hough transform requires a long scan period and a large amount of computation,it is proposed to use the modified Hough transform method for track initiation in three scan periods.This method greatly improves the initiation speed of the target track.
