摘要

平面近场测试中近远场变换得到的远场方向图实际上是相对于某个特定坐标系来定义的。由于实际的需要,远场方向图需要在不同的坐标系之间变换。文章基于近远场变换原理,首先给出了远场方向图在不同坐标系中的公式,然后通过实际测试,对结果进行了验证,结果对比证明了变换理论的正确性与有效性。
        the far-field pattern obtained by the near-to-far field transformation in PNF measurement is actually defined by a special coordinate system. Because of the actual need, the far-field pattern is needed to be transformed between different coordinate system. Base on the principle of near-to-far filed transformation, the formulas of far-field pattern in different coordinate system is presented in this paper. Then, the results are tested by actual measurement. The results comparison proves the correctness and validity of the transformation theory.
