This technical note analyzes the possibility of performing radar Doppler processing with ultra-wideband UWB impulses. This is a departure from traditional Doppler radar implementation, which typically uses narrowband pulses. The theory of Doppler processing with UWB impulses is first presented, followed by an analysis of the Doppler resolution. Some simple simulated examples are included, involving both baseband and modulated UWB impulses. The major drawback of this technique consists of the fact that the Doppler resolution degrades proportionally with the target velocity. Consequently, this type of processing could only be applied to slow-moving targets.
