摘要
Abstract
The rapid rise of new technology represented by meta materials has heavily promoted the radome progress.Different from the usual radome,the meta material radome improves the scattering performance of the array system significantly.For a long time the transmission performances have been attracted attention while the scattering performance neglected instead.The reason is due to that the requirement for the controlling of scattering performance is not urgent on one hand and it is too difficult to conduct accurate analy-sis at the cost of much effort and time especially for the large electric scale radome.Although the high frequency optics approximation method has fair accuracy in analyzing the transmission performance meeting the requirement of design,there is obvious deviation in analyzing the scattering performance unable to meet the requirement of design.For the requirement of the analysis of meta radome scattering problem,the comparison of computation of dielectrics radome by different method is given and the mechanism is analyzed first and the radar cross section(RCS)of meta radome are then analyzed by using characteristic model combined with full wave meth-od.The simulations are compared with the experiment that shows good agreement in contour.It is also found that the RCS reduction of radome is significant when absorbing structure is applied.It can be provided for meta radome designer as reference.关键词
