Abstract
This paper proposes a composite preamble structure based on the fusion of the original Ultra Wide Band (UWB) preamble structure and the Nonlinear Frequency Modulated (NLFM) pulse signal to improve the range-sensing ability of the UWB signal. We focus on improving the range-sensing performance of UWB signals with composite preamble structure. The short-time NLFM signal is utilized in the composite preamble structure to locate the target, so as to lower the target misjudgment rate. Simulation results show that the UWB signal with a composite preamble structure improves the target detection accuracy and reduces probability of target misjudgment, outperforming the original UWB signal.
