摘　　要：通过对成一定角度的双基线进行定位时相位差正确解模糊条件的推导,得出达到最佳效果时方位角与基线夹角的关系。并对相位解模糊的“长短基线配合使用”和“两长基线组合使用”两种方法进行了分析,仿真比较了干涉仪测量精度、噪声方差、信噪比和正确解模糊概率的关系,给出了分析结果。By deriving the conditon of correct resolving phase ambiguity when locating with two baselines, the relation between the azimuth angle and the angles of baselines has been got. The two methods Using Long Baseline Matched with Short One and Using Two Long Baselines＇ in resolving phase ambiguity have been analyzed. And the relations between the measurement accuracy of the phase interferometers, the variance of noise, the SNR and the probability of correct resolving ambiguity have been simulated.
