无源定位技术发展及其展望
Development and Prospects of Passive Positioning Technology
摘要
Abstract
With the continuous evolution of the smart information society and the advancement of smart city construction,the demand for the accuracy and reliability of electronic device positioning is becoming increasingly prominent.Especially in the context of the Internet of Things,the requirements for positioning accuracy and quality have become more urgent.Passive localization technology,due to its strong concealment,low power consumption,and resistance to perception and interference,is widely applied in various fields.Especially in recent years,the introduction and development of Integrated Sensing and Communication(ISAC),machine learning,ambient backscattering and intelligent reflecting surfaces provide new opportunities for the application of passive positioning in 6G.Based on this,firstly the characteristics and classification of passive positioning technology are elaborated.Secondly,according to the parameterized classification method,the passive positioning method and the influencing factors of error are summarized and sorted out.Furthermore,the advantages of multi-parameter fusion passive localization schemes are discussed.Finally,the typical application scenarios,potential technologies,challenges and future research directions of passive positioning technology under the new vision of 6G are prospected.关键词
