利用一种圆滑斜坡函数作为内插函数,可以将测量出的多极化波导模拟器的有限的、离散的扫瞄点的阻抗特性(包括交义极化的相互影响)扩展到整个扫瞄空域。内插是在两个多极化波导模拟器的测量结果基础上进行的。内插结果与该阵的理论计算曲线(该曲线已由实验验证是正确的)相比较发现,在给定模拟器尺寸足够大时(即模拟点足够多),在全扫瞄空域两者一致性很好,内插误差很小。即使是在与电场极化方向相平行的扫瞄面上(该面不能模拟此种极化),结果也是很好的。从而证明了这种内插法用于多极化多元波导模拟器,对予测在全扫瞄空域内各种极化状态下的阵反射特性的有效性。同时,通过对反射特性的予测,也可推算出阵在两个主扫瞄面上阵的单元方向图。因此,利用这种内插法可以大大扩展多极化多元波导模拟器的用途,成为研究和设计多极化相控阵的重要工具。显然,这种方法对单极化也是完全适用的,因它是多极化的一种特例。
Using a sleek ramp function as an interpolation function, the impedance properties of the measured, discrete scanning points of the measured multi-polarization waveguide simulator (including the cross-talk of reciprocal polarization) can be extended to the entire scanning airspace . Interpolation is based on the measurements of two multipole waveguide simulators. The result of the interpolation is compared with the theoretically calculated curve of the array (the curve has been verified experimentally). When the given simulator is large enough in size (that is, the simulation point is large enough), both of them are consistent in the whole scanning airspace Good sex, interpolation error is small. The result is good, even on a scan plane that is parallel to the polarization of the electric field (the plane can not model this polarization). It proves that this interpolation method is applied to the multipolarization multivariate waveguide simulator, which is effective in predicting the array reflection characteristics under various polarization states in a full-scan airspace. At the same time, by predicting the reflection characteristics, the cell patterns arrayed on the two main scan planes can also be deduced. Therefore, the use of this interpolation method can greatly expand the use of multi-polarization multivariate waveguide simulator, become an important tool for the study and design of multi-polarization phased array. Obviously, this method is also perfectly applicable to unipolarization, as it is a special case of multipolarization.
