Two-dimensional imaging of a pedestrian using multiple ultra-wideband Doppler interferometers using clustering-based echo association

چکیده
This paper presents a method of imaging a twodimensional section of a walking person using multiple ultrawideband Doppler radar systems. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The signal received using each antenna is processed employing time– frequency analysis, which separates targets in the time–range– velocity space. This process is followed by a direction-of-arrival estimation employing interferometry. The data obtained using the multiple radar systems are integrated using a clustering algorithm and a target-tracking algorithm. Through realistic simulations, we demonstrate the remarkable performance of the proposed imaging method in generating a clear outline image of a human target in unknown motion. key words: ultra-wideband, radar imaging, Doppler radar, target velocity, human body

متن کاملPedestrian Imaging Using UWB Doppler Radar Interferometry
The imaging of humans using radar is promising for surveillance systems. Although conventional radar systems detect the presence or position of intruders, it is difficult to acquire shape and motion details because the resolution is insufficient. This paper presents a high-resolution human imaging algorithm for an ultra-wideband (UWB) Doppler radar. The proposed algorithm estimates three-dimens...
متن کاملAccurate and Real-Time Pedestrian Classification Based on UWB Doppler Radar Images and Their Radial Velocity Features
The classification of human motion is an important aspect of monitoring pedestrian traffic. This requires the development of advanced surveillance and monitoring systems. Methods to achieve this have been proposed using micro-Doppler radars. However, reliable long-term data and/or complicated procedures are needed to classify motion accurately with these conventional methods because their accur...
