Abstract
Sampling pulse is the key factor affecting the performance of ultra wideband (UWB) radar fuze receiver. Based on the analysis of working principle of sampling integral differential circuit, the mathematical models of frequency domain and time domain are established. Considering the Doppler effect in time domain, a time domain simulation method of the output signal of UWB radar fuze receiver based on Matlab is proposed. The simulation results of the influences of sampling pulse width and amplitude on output waveform show that when the circuit is completely symmetrical, the amplitude of the output signal is only related to sampling pulse width, but not in a monotonic relation. When the circuit is unsymmetrical, it generates a pulse signal before steady state, and the amplitude of the pulse varies proportionately with the amplitude of the sampling pulse but inversely with the width of the sampling pulse.
