摘　　要：建立了雷达发射机中的间歇振荡器的非线性数学模型,利用相空间图、功率谱分析法、平均位移法和Lyapunov指数对该模型仿真产生的时间序列和实测信号进行了分析,理论和实验结果表明,间歇振荡器所产生的高频脉冲序列具有混沌特性,所推导的数学模型和分析结果具有普适性。A nonlinear model of blocking oscillator, which belongs to the transmitter of X type radar, is proposed. The time series simulated by this model and real tested signals are analyzed by means of the Phase Space Graph, Power Spectrum Density (PSD), Average Displacement and Lyapunov Exponents. It is theoretically and experimentally proved that the high frequency pulses generated by blocking oscillator possess the chaotic property. The derived model and corresponding analysis result have a broad generality.
