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 ...

Automatic Arm Motion Recognition Based on Radar Micro-Doppler Signature Envelopes [PDF]
IEEE Sensors Journal, 2020 In considering human-machine interface (HMI) for smart environment, a simple but effective method is proposed for automatic arm motion recognition with a Doppler radar sensor. Arms, in lieu of hands, have stronger radar cross-section and can be recognized from relatively longer distances.

Improving radar performance with constant envelope multi-level chirp
Tehnički glasnik, 2019 M-level Continuous Phase Chirp Modulation is considered for data transmission. In this article, we would like to propose a new approach to transmitting information with the help of multi-level wave guide signaling. The main problem with the classic chirp modulation system is that the final phase of the signal is not equal in each period to the initial ...

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

A Robust and Fast Imaging Algorithm with an Envelope of Circles for UWB Pulse Radars [PDF]
IEICE Transactions on Communications, 2007 Target shape estimation with UWB pulse radars is a promising imaging technique for household robots. We have already proposed a fast imaging algorithm, SEABED, that is based on a reversible transform BST (Boundary Scattering Transform) between the received signals and the target shape.

Non‐Rayleigh Statistics of Ultrasonic Backscattered Echo from Tissues [PDF]
, 1994 The envelope of the backscattered signal from tissues can exhibit non‐Rayleigh statistics if the number density of scatterers is small or if the variations in the scattering cross sections are random. The K distribution which has been used extensively in

Strain‐based modeling and analysis for rock blasting and geomechanics applications
Deep Underground Science and Engineering, EarlyView.This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

ENVELOPE FLUCTUATIONS DISTRIBUTION OF SIMPLE RADAR PULSE BACKSCATTERING IN RARIFIED MEDIUM
Civil Aviation High TECHNOLOGIES, 2017 The basis of modern radar techniques is the direct use of radio-physical data on the power of backscattering. At the same time, the data volume received from the radar allows us to form new estimates and essentially specify classical ones. Significant steps have been made in this direction, using, for example, phase (Doppler) methods.
