Abstract : The detection of ultra-wide-band (UWB) radar signals is considered. Conventional radar theory is examined in the context of ultrawideband signals and extended when necessary. Point target detectors are found for the cases when the additive interference is white Gaussian noise and correlated Gaussian noise or clutter. A conventional moving target indicator (MTI) design is generalized for UWB radar. The effects of bandwidth on the resolution of clutter and target are examined. Optimal and conventional processing are compared for single echo detection. An optimal detector is found for a distributed target with a known target profile. Additionally, optimal detectors are found under two models where only second-order statistics of the target profile are assumed known. Future work areas are suggested.
