| 摘 要： | 提出了一种干涉仪体制下Y型阵列对三维辐射源的瞬时定位方法。该方法基于球面波前模型，利用无模糊相位差测量量，能够实现对雷达辐射源的单脉冲定位。推导了定位方程，分析了该方法的理论定位精度，计算得到GDOP等值线图，并通过Monte—Carlo仿真验证了其有效性和正确性，最后给出了相位差解模糊的工程实现方法并进行了仿真验证。

| Abstract: | An instantaneous ranging passive localization method is discussed, which utilizes Y-shape array phase interferometer structured system. By using the spherical wave model and ambiguity phase differences, the location of an emitter can be detected in a single pulse. The location formula is given out, and the theoretic pre- cision analysis of the method is deduced. By the calculation of the GDOP and Monte-Carlo simulation,the precision distribution characteristics are drawn out. A simple way of resolving the ambiguities of phase differences is introduced. |
