The University of Nebraska has developed a random noise radar system which transmits an ultrawideband random noise waveform with a uniform power spectral density (PSD) in the 1-2 GHz frequency range. Simulation studies and controlled laboratory tests confirm the system's ability to preserve the instantaneous phase of the received signal (Narayanan et al. 1996, 1997). The potential of the system to characterize the Doppler shift of moving targets exhibiting varying linear and rotational velocities was clearly demonstrated (Narayanan et al. 1997). This paper provides with the results of field experiments at a range of about 200 m which confirm the ability of the system to be used as a Doppler radar in operational scenarios.
