【摘要】 近年来,降低天线的雷达散射截面已是电子对抗领域中的重要课题。该文针对已广泛应用的双反射面天线讨论降低其雷达散射截面的方法。结果表明,在保持增益不变的情况下合理选择主反射面的焦距是能够达到降低雷达散射截面的需要的。更多还原

【Abstract】 In recent years, the reduction of Radar Cross Section (R,CS) for antenna has been an important topic in the field of electronic warfare. The way to reduce the RCS of bi-reflective antennas, which have been widely used, in the axial direction is discussed in this paper. The conclusion shows that reasonable selections of the focal distances of the main reflector may be able to obtain low RCS, keeping the high-gain under the antenna unchanged.更多还原
