CHARACTERISATION OF ULTRA WIDEBAND FREQUENCY MODULATED AND STEP FREQUENCY RADAR WITH RANGE GATING

摘要

The similarities and differences between ultra wideband (UWB) frequency modulated continuous wave (FMCW) and step frequency continuous wave (SFCW) are explored. An analytical approach shows that the difference is a small phase error for FMCW. The differences in efficiency and implementation challenges are shown using a radar system capable of running both waveforms. The increased receiver dynamic range of gating the transmitter and receiver for these waveforms are illustrated with the same radar.
