| Abstract: |
| Traditional far-field test method can hardly be used to carry on far field test
of a large phase array because of the difficulty in building a large turntable. To solve the p
roblem，a site method based on artificial source is proposed to test the radiation
pattern. The method uses an airborne platform embarking test system and high
-precision positioning and orientation system to synchronously record the
time, amplitude of the receiving signal and three-dimensional position. Throug
h data processing of the recorded data the radiation pattern can be obtained. Th
e test errors are also analyzed and corrected. Finally, computer simulations are pr
ovided to illustrate the validity of the proposed method. |
