| Abstract: | The working principle, physical simulation test and digital simulation model of a proximity fuze are presented in this paper. Wigner distribution is applied to analyze the instantaneous average power and frequency of Doppler signals, and explosion points are tested so as to validate the digital simulation model of the proximity fuze. The results obtained show that wigner distribution is an effective method for processing the non stationary random signals with variable frequency, such as doppler signal. |
