| 摘 要： | 为研究雷达天线在冲击波作用下的结构变形对天线辐射特性的影响规律,采用LS-DYNA软件计算冲击波作用下天线的结构变形,将获得的变形天线模型导入到FEKO软件中,计算了不同变形下天线的远区辐射场. 根据冲击波与天线的交会方式,分别研究了冲击波正面、反面、倾斜作用下天线辐射方向图的变化. 结果表明,相同距离上冲击波正面作用对辐射方向图的影响比反面和倾斜作用下大.

| Abstract: | To investigate the influence of radiation characteristics of antenna due to its distortion caused by shock wave,the structural distortions of the antennae are simulated by LS-DYNA,and the radiation patterns obtained by FEKO.The models of antennae distortion gained by LS-DYNA are input into FEKO,which calculates the radiation patterns of different distortions of the antennae.According to the encounterod modes of shock waves and antennae,radiation patterns are studied under the three conditions,viz.frontal ac... |
