   Abstract:
   Summary form only given. Planar antennas are photoconductively switched to generate and coherently detect ultrawideband (UWB), transient radiation. This radiation has a bandwidth from 5 to 70 GHz. The antennas are switched photoconductively using a 76-MHz train of 5-ps-duration, 527-nm-wavelength optical pulses generated from a frequency-doubled pulse-compressed mode-locked Nd-YLF laser. The UWB microwave and millimeter-wave radiation generated by these antennas is used to perform UWB transient scattering measurements from resonant targets. Prototype UWB time-domain scattering measurements have been performed using a unique table-top scattering facility. The experimental results are compared with theory. Particular attention is given to the late-time response of targets using such a system
