Human activity recognition by radar sensors plays an important role in healthcare and smart homes. However, labeling a large number of datasets is difficult time-consuming, it for models trained on insufficient labeled data to obtain exact classification results. In this paper, we propose multiscale residual weighted network with large-scale, medium-scale, small-scale networks. Firstly, MRW image encoder used extract salient feature representations from all time-Doppler images through...

Abstract The French micro‐satellite DEMETER was launched on June 29, 2004 in a polar and circular orbit with an altitude of about 665 km. main objective the satellite is to research ionospheric disturbance related seismic activities. This paper reports anomalies observed by within one week before M s 8.0 Wenchuan Earthquake (31.02°N, 103.37°E) which occurred at 06:28 UT May 12, 2008. observation results include: (1) Electron density, electron temperature oxygen ion density changed sharply...
