针对五单元圆型天线阵干涉仪测向系统，分别对等基线和不等基线的结构和相位模糊进行了分析；通过对多基线测量数据的加权处理提高测向精度，提出了权系数的选择方法和测向信号处理算法，其中包括相位差估计、角度变换、解模糊和接收通道误差校正等；计算机仿真结果表明两种结构基线的测向精度非常接近，在全方位、超短波频段内的最大测向误差小于0.10。
English Description：
For the direction finding system of five element circular antenna array interferometer, the structure and phase ambiguity of equal baseline and unequal baseline are analyzed respectively; Through the weighted processing of multi baseline measurement data, the DF accuracy is improved, and the selection method of weight coefficient and DF signal processing algorithm are proposed, including phase difference estimation, angle transformation, deblurring and receiving channel error correction; Computer simulation results show that the direction finding accuracy of the two baselines is very close, and the maximum direction finding error in omni-directional and ultrashort wave band is less than 0.10
