超宽带脉冲作用下抗干扰器件的特性分析OACSTPCD
Characteristic analysis of anti-jamming device under ultra-wide bandwidth pulse
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 pulses for RF links is more and more limited.Ultra-wideband electromagnetic pulse has become a new type of interference means 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-jamming performance of adaptive zeroing…查看全部>>
