Global navigation satellite system (GNSS)reflected signals have been widely used in remote sensing applications. To overcome the low-power budget of GNSS reflected signals, traditional detection strategies involve extending the coherent processing interval (CPI) of a single frame or employing the multiframe detection (MFD) method in which the noncoherent integration is used to accumulate echo ener...Show More
This paper investigated the feasibility and reliability of employing various physiological measures - for determining drivers’ fatigue levels, which may ultimately lead to a solution for real-time detection of driver fatigue state for improving driving and traffic safety. An experimental study was conducted to collect the data, including fatigue levels assessed via the Karolinska sleepiness scale ...Show More
Owing to the global coverage and high visibility of global navigation satellite systems (GNSS), passive radar using GNSS satellites as transmitters of opportunity has shown great potential for moving target detection, and its possibility to detect short-range maritime targets has been verified. Nevertheless, the existing methods always require tens of seconds for echo integration, which is not ide...Show More
