Feasibility Study of Using 5G Signals for Illumination Purposes in Passive Radar

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника
Introduction. Passive radars perform target detection based on reflected signals emitted by third-party transmitters. The absence of its own transmitter determines the main advantages of passive radars compared to conventional active radars: lower cost ...

Signals of Opportunity for Atmospheric Remote Sensing [PDF]

open access: yes, 2017
To obtain the crucial information about the boundary layer(Troposphere), there is a need for measurement of large areas(>25,000 km2) with ne scale measurements of less than 1-2 km area. Over the past years, several methods have been developed to measure atmospheric water vapour fields, but none of them provide information on such small scales(< 1-
