Abstract. Ground-based radar precipitation products typically need adjustment with rain gauge accumulations to achieve a reasonable accuracy. This is certainly the case for the pan-European radar precipitation products. The density of (near) real-time ... a potentially interesting (complementary) source to merge with radar precipitation accumulations. Here, a 1-year personal weather ... after aggregating to 1 h accumulations, using unadjusted radar data. The PWS 1 h gauge accumulations are employed to spatially adjust OPERA radar accumulations, covering 78 % of geographical Europe. The performance ...

Modern monostatic radar-based human activity recognition (HAR) systems perform very well as long as the direction of human activities is either towards or away from the radar. The monostatic single-input single-output (SISO) and monostatic multiple-input multiple-output (MIMO) radar systems cannot detect motion of an object that moves perpendicularly to the radar's boresight axis. Due to this physical layer limitation, today's radar-based HAR systems fail to classify multi-directional ... propose a HAR system underlying a distributed MIMO radar configuration, where multiple antennas of a millimeter wave ...
