基于相位差变化率的单站无源定位算法研究

在不断发展的无源定位技术中,单站无源定位技术得到快速提升。出现了测向定位、多普勒频率定位、到达时间定位、多普勒频率变化率定位、相位差变化率定位等多种单站无源定位算法。本文针对这几种定位方法进行介绍和分析,并结合实际项目需求,最终选择相位差变化率定位法,并对其进行详细研究。

In the continuous development of passive location technology,single-station passive location technology has been rapidly improved.There are a variety of single-station passive positioning algorithms such as direction measurement positioning,Doppler frequency positioning,arrival time positioning,Doppler frequency change rate positioning,and phase difference change rate positioning.This paper introduces and analyzes these positioning methods,and selects the phase difference change rate method based on the actual project requirements,and studies it in detail.
