Pilot‐based detection for DVB‐T passive coherent location radars [PDF]
IET Radar, Sonar & Navigation, 2020 This study investigates the feasibility of pilot‐based detection for passive coherent location (PCL) radars exploiting digital video broadcasting‐terrestrial (DVB‐T) signals. The DVB‐T signal is formed by two parts: a data signal and a pilot signal. The parameters of the pilot signal are known thanks to the DVB‐T standards that permit the generation ...

Specificity and coherence of body representations [PDF]
, 2009 Bodily illusions differently affect body representations underlying perception and action. We investigated whether this task dependence reflects two distinct dimensions of embodiment: the sense of agency and the sense of the body as a coherent whole.

Polar firn properties in Greenland and Antarctica and related effects on microwave brightness temperatures [PDF]
The Cryosphere, 2023 In studying the mass balance of polar ice sheets, fluctuations in firn density near the surface is a major uncertainty. In this paper, we explore these variations at locations on the Greenland Ice Sheet and at the Dome C location in Antarctica.

Beamforming of LOFAR Radio-Telescope for Passive Radiolocation Purposes
Remote Sensing, 2021 This paper presents the results of investigations on the beamforming of a low-frequency radio-telescope LOFAR which can be used as a receiver in passive coherent location (PCL) radars for aerial and space object detection and tracking. The use of a LOFAR
