| 摘要: |
| 在分析某型近炸引信的工作原理和数字仿真模型的基础上，应用瞬时谱方法分析多普勒信号的瞬时平均频率，验证了近炸引信的数字仿真模型.结果表明瞬时谱是分析多普勒信号这类时变频非平稳随机信号的有效方法。 |

| Abstract: |
| In this paper，the working principle and computer simulation model of proximity fuze of some type are introduced，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 signal with time-varying frequency such as Doppler signal. |
