摘要
介绍了近炸引信的工作原理、物理仿真试验和数字仿真模型。应用瞬时谱方法分析了多普勒信号，其瞬时平均功率和平均频率，并对炸点进行了检验，从而验证了近炸引信的数字仿真模型。表明瞬时谱估计是分析时变频非平稳随机信号的有效方法。
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.
