Abstract

We present results of ranging by using subpicosecond, freely propagating electrical pulses. In the frequency domain this corresponds to extremely-wide-bandwidth pulses with frequencies extending beyond 1 THz. Such temporally short, wide-bandwidth pulses are advantageous for ranging studies for several reasons. First time-gated detection allows extremely high discrimination of the reflected wave from the target from unwanted reflections. Such spurious reflections are a serious concern in cw ranging experiments. Secondly, the short wavelengths used in terahertz ranging permit the use of scale models in determining radar signatures of real-world targets. For example, X-band radar in the range 8-12 GHz has a wavelength of ~3 cm, corresponding to a 1:100 scale factor for terahertz ranging studies. Finally, the broad bandwidth of the terahertz ranging system permits the determination of scattering cross sections at many frequencies simultaneously.
