摘　　要：基于高重频超宽带脉冲,研究了高重频超宽带脉冲对自适应调零天线和PIN限幅器的抗干扰性能的影响。基于Matlab和ADS仿真软件搭建模型,并通过实验平台对ADS的仿真结果进行验证。实验结果表明:对于导航接收机中的自适应调零天线,超宽带干扰脉冲会使其射频链路产生饱和效应,从而使功率倒置算法失效,进而无法在干扰方向形成零陷;对于PIN限幅器,超宽带干扰脉冲可以使其产生明显的尖峰泄露效应。相较于ns量级的窄谱高功率微波脉冲,超宽带脉冲对限幅器的干扰能力更强。With the continuous development of anti-jamming devices,the jamming effect of interference pulsesfor RF links is more and more limited.Ultra-wideband electromagnetic pulse has become a new type of interferencemeans with its own wide spectrum and steep rising edge characteristics.Based on the high re-frequency ultra-wideband pulse,this paper investigates the effect of high re-frequency ultra-wideband pulse on the anti-jammingperformance of adaptive zeroing antenna and PIN limiter.The model is built based on Matlab and ADS simulationsoftware,and the simulation results of ADS are verified by the experimental platform.The experimental results showthat:for the adaptive zeroing antenna in the navigation receiver,the UWB interference pulse can cause saturationeffect on its RF link,which makes the power-inversion algorithm invalid,and then zero-trapping can not form in thedirection of the interference;for the PIN limiter,the UWB interference pulse can cause an obvious spike leakageeffect.Compared to narrow-spectrum high-power microwave pulses on the nanosecond scale,UWB pulses are morecapable of interfering with limiters.
