低空监视技术及其发展趋势综述
Review on Low-Altitude Surveillance Technology and Its Development Trend
摘要
Abstract
With the continuous reforms of low-altitude economy,the advancement of low-altitude aircraft are presenting a new landscape characterized by high density,heterogeneity,autonomy,and mixed manned/unmanned operations.Low-altitude surveillance,as an important safeguard for the safety of low-altitude operations,can ensure the safe and efficient operation of aircraft at low altitudes.To address current issues of inadequate low-altitude surveillance means,it is necessary to construct a low-altitude surveillance technology system with no blind spots,covering mixed manned/unmanned operations,based on the characteristics of the complex low-altitude environment.Firstly,current difficulties in low-altitude surveillance are analyzed from the perspectives of the concept of low-altitude surveillance and its development trends,including weight,size and power limitations of airborne equipment,tight channel resources,and significant differences among aircraft.Secondly,from the perspectives of the cooperative surveillance technology and the non-cooperative surveillance technology,the current status of key surveillance technologies worldwide is elaborated,and a systematic comparison and summary of the relevant characteristics of each technology are provided.Finally,facing the development of a new generation of low-altitude surveillance,the development directions of future cooperative surveillance,non-cooperative surveillance,and integrated surveillance technologies are discussed,with the expectation of providing certain guidance for the safe operation of low-altitude aircraft in the future.关键词
