提出了通过相位差计算入射角的方法。不再将正弦函数作为相位差与入射角的关系,而是通过数据拟合的方法求出两者的函数关系,从而减小了相位差斜率线性度差带来的测向误差。通过综合分析不同基线的多个模糊角的相互关系解决了测向模糊的问题,使布阵更具灵活性。仿真和实测结果显示,该方法能解模糊,并提高测向精度。

A new method of resolving incident angles in direct finding based on interferometer is presented. Linearity of phase difference against incident angle is modified by data fitting tech-nique and accuracy of direct finding is improved consequently. Comprehensive analysis of multi-ple incident angles resolved by corresponding phase differences of base lines is conducted to a-void angle ambiguity. Simulations and measurements demonstrate the validity and accuracy of this method.
