UWB waveforms and coding for communications and radar

The author describes the efforts of Time Domain Systems Incorporated (TDS), a small company specializing in the development of RF monocycle waveform applications. the areas of application are primarily short-range communications and radar. Monocyclic RF is a subset of ultrawideband (UWB) electromagnetics. UWB signals are defined as having greater than 25% relative bandwidth as defined by BW/f/sub c/. Single RF cycles easily qualify with bandwidths of approximately 100% TDS's focus is on RF monocycles with periods from a few nanoseconds down to tens of picoseconds, corresponding to centre frequencies of 200 MHz to 20 GHz.<
