Two-Dimensional Imaging of a Pedestrian Using Multiple Wideband Doppler Interferometers with Clustering-Based Echo Association

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

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 tar...

False Image Suppression in Two-Dimensional Shape Estimates of a Walking Human Using Multiple Ultra-Wideband Doppler Radar Interferometers

Accurate two-dimensional imaging of a human body in motion using multiple ultra-wideband Doppler radar systems in a multipath environment

This paper presents a method of imaging a two-dimensional section of a walking person using multiple ultra-wideband Doppler radar systems. By exploiting multipath echoes, we can increase the effective number of radar systems virtually. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The data...

Pedestrian 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...

Accurate 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...
