| Abstract: | In this paper, the working principle and computer simulation model of proximity fuze of some type areintroduced, Wigner distribution is applied to analyse the instantaneous average frequency of Doppler signal, so as to validate the model. The result shows that Wigner distribution is an effective method to process the nonstationary signalwith time-varying frequency such as Doppler signal. |

| Keywords: | proximity fuze Wigner distribution simulation model validation. |
