一种临近空间高超声速目标航迹起始算法
A Track Initiation Method for Near Space Hypersonic Target
摘要
Abstract
An improved modified Hough transform track initiation method based on the Doppler knowl-edge in three-dimensional space is proposed.As for near space hypersonic target,the traditional track initia-tion leads to an increase in false tracks and is easy to lose tracks.The algorithm proposed in the paper uses constraints and Doppler information to eliminate part of clutters first,and then the modified Hough trans-form is applied.This method not only can make track initiation effectively,but also greatly decrease the false tracks.The Monte Carlo simulation shows that the method can initiate track fast and effectively and is a practical method for near space hypersonic target.关键词
