چکیده
Ultra-wideband (UWB) signals originated from research and development work on high resolution radiofrequency (RF) radar systems in the 1950-60s. The current FCC regulations in the US, define a UWB signal as having an absolute bandwidth which exceeds 500 MHz or fractional bandwidth over 20%. The FCC frequency band assigned to UWB systems extends from 3.1 GHz to 10.6 GHz, i.e. a bandwidth of 7.5 GHz centred at 6.85 GHz.

3-Dimensional Imaging and Motion Estimation Method of Multiple Moving Targets for Multi-Static UWB Radar Using Target Point and Its Normal Vector
Radar systems using ultra-wideband (UWB) signals have definitive advantages in high range resolution. These are suitable for accurate 3-dimensional (3-D) sensing by rescue robots operating in disaster zone settings, where optical sensing is not applicable because of thick smog or high-density gas. For such applications, where no a priori information of target shape and position is given, an acc...
متن کاملA Fast Algorithm for 3-Dimensional Imaging with UWB Pulse Radar Systems
Ultra-wideband pulse radars are promising candidates for 3-dimensional environment measurements by autonomous robots. Estimating 3-dimensional target shapes by scanning with an omni-directional antenna is an ill-posed inverse problem. Conventional algorithms such as the synthetic aperture method or parametric algorithms have a problem in terms of their calculation times. We have clarified the e...

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...
