| 摘 要： | 在已建立的晶体管自差机等效电路模型的基础上,运用谐波平衡法,研究了多普勒无线电引信自差收发机受迫振荡的非共振振荡特性,推导出了自差收发机在不同强度信号作用下的幅频特性. 在非共振状态下,系统的定常振荡为强迫振荡项和自由振荡项之和. 仿真结果表明,弱信号使自由振荡项趋于一个非零的定常振幅,大信号使得自由振荡项衰减为零,而小信号则使某些频率区域中的振荡情况更复杂.

| Abstract: | Based on an equivalent circuit model of transistor autodyne,the non-resonance oscillation characteristics of the forced oscillation of autodyne are analyzed using the harmonic balance method.With different jamming signals,different frequency amplitude response properties of the autodyne are obtained.Steady-state oscillation occured on the combination of constrained oscillation and free oscillation in the instance of non-resonance oscillation.The results of simulations indicate that the amplitude of the free oscillation goes to a stable nonzero with a weak jamming signal and turns zero with a strong jamming signal,but the oscillation within the bounds of some frequencies is complex with a small(jamming) signal. |
