    摘要:

    提出了一种毫米波干涉仪二维测向解模糊算法.通过对圆形阵列阵元与参考阵元之间的测量相位差进行一次或多次虚拟变换运算, 获得虚拟阵元与参考阵元之间的无模糊相位差.无模糊相位差被用来得到粗略无模糊的波达方向估计, 此粗略无模糊的波达方向估计被用来解原阵列阵元和参考阵元的周期性相位模糊.进而获得高精度波达方向估计.仿真实验表明,所提算法在毫米波频率范围内能获得高精度的二维测向结果.

    Abstract:

    A two-dimensional direction finding ambiguity resolution algorithm about millimeter wave interferometer is proposed in the paper. By means of implementing one or more times virtual transformation operation on measured phase differences between the original circular array elements and the reference array element, the unambiguous phase differences between the virtual array element and reference array element are achieved. The unambiguous phase differences are used to give rough but unambiguous estimation of direction of arrival (DOA), which are used as coarse references to disambiguate the cyclic phase ambiguities in phase differences between the original array element and the reference array element. The high-precision estimations of DOA are acquired. Simulation examples have verified that the algorithm can obtain the two-dimensional direction finding results with high accuracy in the millimeter wave frequency range.
