Uwb Short Range Imaging
نویسندگان
چکیده
One of the main concerns when imaging extended real objects is the capacity of the system to correctly reconstruct the object cross section electric properties. In this paper, the imaging capabilities of an UWB short range system are analyzed, based on the Multifrequency Bi-Focusing Imaging (MFBF) and Time Difference of Arrival (TDOA) techniques, and its capability to reconstruct high contrast objects are studied. Based on an analytical formulation for a dielectric cylinder the different spatial and frequencial sampling criteria have been verified and its behaviour for highly contrasted objects has been obtained. An experimental validation has been finally performed using two collinear arrays of antennas working in transmission and reception respectively.

Ultra-Wideband Waveform Generation Using Nonlinear Propagation in Optical Fibers
Ultra-wideband (UWB) radio is a transmission technology that is based on short pulses, whose spectral width is on the order of several GHz. UWB signals are free of sine-wave carriers, and their duty cycle and power spectral density are low. These characteristics provide UWB radio with unique advantages: improved immunity to multi-path fading, increased ranging resolution, large tolerance to int...

Ultra-wideband (UWB) pulse radars have a definite advantage in high-range resolution imaging, and are suitable for short-range measurements, particularly at disaster sites or security scenes where optical sensors are rarely suitable because of dust or strong backlighting. Although we have already proposed an accurate imaging algorithm called Range Points Migration (RPM), its reconstructible are...

متن کاملCognitive Radio for Short Range Systems based on Ultra-Wideband
Cognitive Radio (CR) has been proposed as a promising and effective technology to improve radio spectrum utilization. It can change its transmitter parameters depending on the environment in which it operate based on interaction. In CR, a number of different methods of spectrum sensing are used to identify the presence of signal transmission. Among them, the multitaper method (MTM), has been in...
