Abstract
This paper systematically evaluates the performance potential of ultra-wideband (UWB) radar systems for Moving Target Detection (MTD) in strong clutter. Based on a general data model for UWB multiple phase waveforms, we first derive the waveform-based optimum UWB processor which represents the maximum achievable performance of UWB systems. The UWB gains/losses are individually identified by careful performance comparisons with narrowband systems. Our study results show that UWB systems potentially have a significant MTD performance gain, in addition to the well-known clutter and fluctuation reduction. This additional gain indicates that the subclutter visibility performance of UWB surveillance systems is severely underestimate in the existing literature.
