改进的随机Hough变换抛物线运动目标航迹起始算法
A Novel Algorithm of Initiating the Moving Target Along the Parabolic Track Based on Improved Randomized Hough Transform
摘要
Abstract
In order to solve the problem of the Track Initiation of dim target with constant acceleration along parabolic curve, a new speedy Track Initiation algorithm based on improved Randomized Hough Transform (RHT) was proposed in this paper. This algorithm makes use of the speed direction of two points picked randomly and the location information of third point searched to calculate the parabola parameters, and the coordinate transform was applied to reduce the dimensions of the vote parameters space in order to speedily initiate the track of multitarget with constant acceleration. As a result, the problems of invalid sample and accumulation were well solved. Compared with the traditional Initiation track methods based on the five points, the simulation results show that the novel method has the advantage of higher speed and lower false alarm probability.关键词
