UAV Detection Using Continuous Wave Radar
2018 IEEE International Conference on Information Communication and Signal Processing (ICICSP), 2018In this paper we use a continuous wave radar to detect unmanned aerial vehicles (UAVs). The proposed method can be divided into two stages: suspected targets extraction and trajectories obtaining. In the first stage, we use a Double-GMM-Iteration method, in which two Gaussian mixture model background subtractors are applied to remove the background and

Local Pulse Wave Detection Using Continuous Wave Radar Systems
IEEE Journal of Electromagnetics, RF and Microwaves in Medicine and Biology, 2017Although a lot of research has been done into radar-based heartbeat detection over the past few years, it is still unknown which physiological effects truly underlie these measurement signals. This paper investigates the cardiovascular system, as well as the effects due to the antenna characteristics, and establishes a connection to the variety of ...

Multipath Suppression for Continuous Wave Radar via Slepian Sequences
IEEE Transactions on Signal Processing, 2020In continuous wave (CW) radar systems, multiple signal copies impinge the receiver simultaneously. Often, undesired multipath and direct-path copies are many times stronger than potential targets. When applying matched filter signal processing techniques,

On the Impact of System Nonlinearities in Continuous-Wave Radar Systems for Vital Parameter Sensing
Topical Conference on Wireless Sensors and Sensor Networks, 2020This paper investigates the influence of nonlinearities on relative distance measurements by continuous-wave radar systems. For the case of a six-port receiver architecture, a mathematical relationship between detector nonlinearity and measurement error ...
