A novel coherent ultra-wideband radar system operating inthe 1- to 2-GHz frequency range has been developed recently at theUniversity Nebraska. The transmits white Gaussiannoise. Detection and localization buried objects is accomplished bycorrelating the reflected waveform with a time-delayed replica thetransmitted waveform. Broadband dual-polarized log-periodic antennasare used transmission reception. unique signal-processingscheme inject coherence into by trans-lation ultrawideband signal 160-MHz phase-lockedsource prior performing heterodyne correlation. coher-ence allows extraction target’s polarimetric amplitude phasecharacteristics. This paper describes design features theradar system, develops theoretical foundations noise polarimetry,provides experimental evidence resolution capa-bilities demonstrates results obtained in subsurfaceprobing applications.
