## Rotating Interferometer-based Algorithm for Parameter Estimation of Near-field Source

• 摘要: 该文基于旋转干涉仪提出了一种新的近场源参数估计算法.该算法利用单个长基线干涉仪的旋转和相位积分实现相位解模糊,有效解决了单基线干涉仪在近场源情况中存在的无模糊视角范围和测角精度之间的矛盾.该算法只需两个接收天线即可得到近场源俯仰角、方位角和距离参数的闭式解,无需构造高阶累积量矩阵和多维搜索,同时也降低了多基线组合对通道一致性的要求.相比于传统的双长基线干涉仪方法,该文算法具有更高的参数估计精度和解模糊能力,具有结构简单、易于工程实现的优点.计算机仿真实验表明了所提算法的有效性和正确性.
