A method based upon simple diffraction theory is described for the calculation of modified paraboloid reflectors to produce from a point source a shaped beam of arbitrary shape in one plane and uniformly narrow in the perpendicular planes. A specific application of the shaped beam antennas is in connection with radar antennas designed for height finding. In this case the antenna must have a sharp elevation beam for obtaining precise elevation information and a rapid elevation scan. The beam must be relatively...

A method based upon simple diffraction theory is described for the calculation of modified paraboloid reflectors to produce from a point source a shaped beam of arbitrary shape in one plane and uniformly narrow in the perpendicular planes. A specific application of the shaped beam antennas is in connection with radar antennas designed for height finding. In this case the antenna must have a sharp elevation beam for obtaining precise elevation information and a rapid elevation scan. The beam must be relatively broad in azimuth in order that the target will be held in the beam long enough to obtain height information. If a fixed minimum of illumination is to be achieved at a given linear distance on both sides of the center line of the azimuth beam, the amplitude pattern must have the so-called "double cosecant" or "beavertail" shape.

本论文讨论如何利用简单衍射理论,计算改良抛物面反射器天线幅射之图型。此反射器可将一无方向性辐射源之能量聚集于任何形状之波束中。此原理可以应用在地面上或船面上寻求飞机高度雷达天线之设计。在此类雷达中,天线之方位图型必须为“双馀割平方”式;其特性为自波束对称轴线起,至其两端,辐射一次路程之功率,与方位角之馀割平方成正比。得此图型之最简易方法为置一狭窄之铅垂金属条于一截形抛物面反射器之中心,金属条之宽度,可改变波束之方向性;其支距,即金属条与反射器之距离,可影响两反射波之位相。故改变金属条之宽度及其支距,可得欲得之图型。 利用衍射及干涉理论,计算金属条及截形抛物面所生之总图型为:在方位面内,幅射强度J_H与水平角θ之关系为: J_H =AA[sin~2(15πsinθ)/(15πsinθ)~2-2(1-cosπ/4)sin(2πsinθ)/2πsinθ(sin(2πsinθ)/2πsinθ-sin(15πsinθ)/15πsinθ)]A为辐射波振幅,A为A之复共轭数。计算之结果与实验之结果,颇为一致。

Micro wve Ienscs using media variable of refractive index have been widely used,such as for a-round scan.The Lens is symmetrical about its center or about its axis.The general properties of such lenses have been stuaied by using.Fermat's Principle and calculus of variations ana by means of Hamiltonianoptics,Both methods base essentially on the same geometrical optical model arising from the fact that electromagnetic waves behave locally as plane waves.The first method has been fully developed by the investigatio of an integral equation of the Abel,s type Subject to various modifications,whilethe second method which may make clearer the properties of such lenses to antenna despners has been studied only scarcely.It is the purpose of this paper to study both methods further and to obtain batin some new micro wave lens designs.

利用折射系数连续变化的媒质做成的微波透镜已经得到了广泛的应用,例如用于全方向扫描中。这类透镜是对中心对称的,或对轴对称,其一般特性已被人们应用费米原理及变分法和应用汉密尔顿光学方法研究过。这两种方法同是基于几何光学的原理,第一种方法归结为一个阿倍尔积分方程的研究,而且已经达到一个相当完善的程度,第二个方法则研究得还不太多。本文对这两种方法进一步加以研究,以求能够得到一些新的微波透镜的设计方案。
