摘　　要：现代相位干涉仪系统进行方位测量时,受限于天线物理尺寸及作战对象特征,基线长度无法满足小于半波长的条件,存在相位差测量模糊的问题。对此,研究一种由双基线干涉仪相位差推导出的相位差模糊图概念,提出基于模糊图的工程化解模糊方法,对其约束区间、判别条件及算法架构进行设计和仿真,验证基于相位差模糊图的干涉仪解模糊算法的工程化有效性。When using modern phase interferometer systems for azimuth measurement,limited by the physical size of the antenna and the characteristics of the combat object,the baseline length can't meet the condition of less than half wavelength,which makes the problem of the phase difference measurement ambiguity.Base on the study on the concept of phase difference ambiguity figure derived from the phase difference of a dual baseline interferometer,this paper presents a fuzzy graph based method for engineering ambiguity resolution,designed and simulated its constraint interval,discriminant conditions and algorithm architecture,verified its engineering effectiveness.
