Abstract
Researching the effect of complex ground on the echo characteristics is important for impulse-radio ultra-wideband (IR-UWB) proximity fuze. In this paper, the mathematical model of mixed medium ground is established by Monte Carlo method to represent complex ground, and the time-domain signal scattering model is established based on the unit decomposition method. The correlation between echo signals of complex ground and single medium ground is studied by using this model, and the complex ground echo signal is analyzed by wavelet time-frequency transform. The simulation results show that, compared with the single medium ground, the complex ground mainly affects the peak amplitude of the echo signal, and has little influence on the peak position. The simulation and analysis provide a 1 theoretical basis for the ranging control of the IR-UWB fuze on the complex ground.
