Pulse Generation and Compression on a Travelling-Wave MMIC Schottky Diode Arraynes in electronics. In particular, due to a balance between nonlinearity and dispersion soliton waves can be generated . which preserve their shape and velocity during propagation representing a compressed pulse of excitation. These unique properties of solitons make them of considerable interest in

This paper discusses measurements of target “echoes” using an impulse UWB system..We first examine the interaction of the transmitted pulse with conductive plates. At small incidence angles, we observe both specular scatteri

An Overview of Sandia National Laboratories’ Plasma Switched, Gigawatt, Ultra-Wideband Impulse Transsupport experimental applications. The sources fall into two different classes, pulse peaking and pulse shorting depending on how the UWB frequency components are generated. The frequency spectrum of the radiated pulse from these sources include the spectrum of 100-MHz to 3-GHz. Depending upon the s

An Impulse Radio Communications System prototype, transmitting high qualiity audio, was tested to ranges in excess of 7 kilometers. The potential range of this type of system at this power level may exceed 20 kilometers. The prototype had a center frequency of 675 MHz and an approximately equal bandwidth. We used a small wideband omni-d
