Introduction. Ultrawideband (UWB) impulse radar uses non-sinusoidal transient signals, which makes time domain analysis a very insightful method to study system behaviour. In this work, a simula-tion model based on time-domain processing for UWB impulse radar is presented and validated with measurements.
This book presents the theory, analysis, and design of ultra-wideband (UWB) radar and sensor systems (in short, UWB systems) and their components. UWB systems find numerous applications in the military, security, civilian, commercial and medicine fields.
1 sty 2014 · Key components are step recovery diode (SRD) based picosecond pulse generators [6], pulse differentiators, a UWB power amplifier, transmitting and receiving antennas, low noise amplifier, UWB ...
9 gru 2020 · The performance of printed wideband antennas has to be optimized both in frequency and time domains, to qualify for UWB applications. This is especially true in multi-resonant antenna topologies where the excitation of different modes can change phase centers and radiation patterns with frequency.
An UWB time domain system has previously been developed at Chalmers University of Technology with the aim of replacing the VNA with a fast, compact and low-cost system performing UWB measurements in the time domain with sufficient accuracy.
28 cze 2018 · To achieve 15 cm resolution, direct time-domain UWB recovery would have to sample at 2 Gsps or faster.
Ultra-wideband (UWB), short-pulse (SP) electromagnetics are now being used for an increasingly wide variety of applications, including collision avoidance radar, concealed object detection, and communications.
