针对单站单脉冲的被动测距问题，提出了一种基于等长基线相位干涉仪的单脉冲定位方法。该方法采用至少3个天线构成等长基线干涉仪对，利用等长基线干涉仪接收到辐射源信号球面波的波前相位2π模糊数相同的原理，通过等长基线相位差的差值和来波方向，确定信号源与观测站之间的距离。在对该算法的基本原理和无模糊定位条件描述的基础上，分析了定位性能，并通过计算机仿真验证了该算法的有效性。

A passive ranging method with a single pulse based on equal-length baseline interferometers is proposed for the passive location system.The method uses at least three antennas to compose equal-length base-line interferometer pair.The phase ambiguity can be canceled out by the phase differences of equal-length base-line interferometers with the same 2πambiguity numbers,and the range of the emitter can be computed by com-bining the direction of arrival.Based on introduction of the theory and unambiguous condition of the method the performance of the algorithm is analyzed and verified by computer simulations.
