双基线干涉仪解模糊能力分析

Analysis on ability of dual-baseline interferometer to resolve angular ambiguities

对双基线干涉仪基于余数定理解相位模糊的能力进行了深入分析及仿真验证,给出了较准确的解模糊能力的数学表达式。仿真结果表明,在基线长度满足余数定理的条件下,仍可通过基线长度的合理设计提高解模糊能力。

A rigorous mathematical analysis of the ability of dual-baseline interferometer to resolve angular ambiguities based on remainder theorem is presented. Theoretical analysis and simulation results show that by properly designing the antenna spacings, it is possible to improve significantly the ability to resolve angular ambiguities under the constraint that the distances between adjacent antenna elements are relatively prime.
