超宽带电阻加载Vivaldi天线的仿真与设计

内容简介：根据应用于隐藏目标探测的冲击脉冲雷达系统对天线的特殊要求,设计并优化出满足要求的收发天线;在分析Vivaldi宽带天线设计方法的基础上,结合冲击脉冲雷达的特点设计了Vivaldi天线,分析了其时域性能及频域性能,并基于遗传算法,研究了一种加载Vivaldi天线形式,有效地抑制了脉冲信号的拖尾,有利于提高目标检测能力。

Abstract：According to the special demand of antennas for the impulse radar in detecting the concealed target,the transmitted-received antennas have been designed and optimized.The Vivaldi antennas are designed based on the analysis and the summary of the traditional Vivaldi antenna＇s design method.And in the time and frequency domain they are analyzed and evaluated combined with the needs of impulse radar.A new model of Vivaldi antenna using certain loading form is designed based on the genetic algorithm.This new model can strongly support the experiment for detecting the concealed targets with an efficient inhibition of the pulse tail.
