本文介绍了在不改变主反射面轮廓前提下，通过移动馈源相位中心，并适当改变主副反射面边缘的照射锥削，再次将副反射面赋形的设计原理及方法。计算和测试结果表明，按此方法设计的天线不仅具有较高的效率，而且有优良的旁瓣特性。
This paper introduces the design principle and method of shaping the secondary reflecting surface by moving the phase center of the feed and changing the irradiation taper of the edges of the primary and secondary reflecting surfaces without changing the profile of the primary reflecting surface. The calculation and test results show that the antenna designed by this method not only has high efficiency but also has excellent side lobe characteristics.
