宽带干涉仪阵列布局设计

A Baseline Design Method of Wideband Interferometer

在受噪声扰动和天线间相位不一致等的影响下,如何设计宽带相位干涉仪布局以使得干涉仪能以尽可能高的概率解模糊,是宽带干涉仪设计中一个重点和难点。从模糊概率数学模型出发,分析了给定解模糊算法下能正确解模糊的条件,并求出最佳的阵列布局。通过仿真验证了该方法的有效性。

When there is an error in phase and difference of phase between channels, it is a dif-ficult and important problem to design the baseline of the wideband antenna array to improve the possibility of solving the ambiguity. This problem with the mathematicalmodel of possibility is an-alyzed. Based on a new solving ambiguity method, the possibility of solving ambiguity of any given baselines is given with mathematical and then the best array layout can be found easily. Finally, the validity of this method is demonstrated with two examples.
