Hand Gesture Recognition based on Radar Micro-Doppler Signature Envelopes [PDF]
2019 IEEE Radar Conference (RadarConf), 2019 We introduce a simple but effective technique in automatic hand gesture recognition using radar. The proposed technique classifies hand gestures based on the envelopes of their micro-Doppler signatures. These envelopes capture the distinctions among different hand movements and their corresponding positive and negative Doppler frequencies which are ...

Dust Formation By Failed Supernovae [PDF]
, 2014 We consider dust formation during the ejection of the hydrogen envelope of a red supergiant during a failed supernova (SN) creating a black hole. While the dense, slow moving ejecta are very efficient at forming dust, only the very last phases of the ...

Precise Radar Target Ranging Estimation Based on Slip Matching of Envelopes [PDF]
Advances in Computer Science Research, 2015 A novel precise radar target ranging method based on echo phases and slip matching of envelopes is presented in this paper. The method provides a high precision with rootmean-square error at sub-wavelength level, and it only requires envelopes of the echo pulses. The difficulty is matching procedure of envelopes. According to the principle of resolving
