【摘要】 研究了连续波多普勒引信自差收发机的牵引振荡特性。由于自差式连续波多普勒引信易受牵引的特点而存在信道泄漏,根据建立的引信自差收发机的高频大信号等效模型,并应用非线性振荡理论分析了其在外加信号作用下的工作状态,得到了引信自差机产生牵引振荡的振幅与频率相对失谐量之间的关系,从而为某些制导武器的末端干扰提供理论依据。更多还原

【Abstract】 The frequency-amplitude characteristic of constrained oscillation of the autodyne in radio proximity fuze is ana- lyzed.An equivalent model of the autodyne is established,which is based on high frequency and strong signal.With a jamming signal,the oscillation state of the autodyne is reconstructed by using the theory of nonlinear oscillation.The relation between the amplitude of the constrained oscillation and the relative nonresonance frequency is gained.更多还原
