雙反射面天線的雷達散射截面
Radar cross section of bi-reflective antenna
-
摘要: 近年來,降低天線的雷達散射截面已是電子對抗領(lǐng)域中的重要課題。該文針對已廣泛應(yīng)用的雙反射面天線討論降低其雷達散射截面的方法。結(jié)果表明,在保持增益不變的情況下合理選擇主反射面的焦距是能夠達到降低雷達散射截面的需要的。

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. -
