Imaging in UWB Sensor Networks
Wireless Sensor Networks: Application-Centric Design
The main characteristic of UWB technology is the use of a very wide frequency range. A system is referred to as UWB system if it operates in a frequency band of more than 500 MHz width, or if the fractional bandwith bw Here f H , f L , and f C denote the upper and lower frequency limit and the centre frequency, respectively. For imaging applications the large bandwidth is of interest because it guarantees a high resolution in range direction, as explained in the next section.
