摘　　要：基于大潜深耐压实心厚壁柱状天线罩模型,提出一种四面阵干涉仪测向算法,推导了该模型下干涉仪相位差及信号入射角度的相关计算公式。该算法可以解决天线罩插入相位移不均匀性引入的相位误差问题。最后通过计算机仿真验证了所提算法的有效性,能够很好地解决经典干涉仪算法在实心壁天线罩模型下带来的阵元相位差严重失真以及测向误差大的问题。An algorithm of four-face array interferometer direction finding based on deep-submergence radome model was put forward in this paper.The detailed formulas of interferometer phase difference and incidence angle were derived as well.The proposed algorithm is able to correct the phase error leading by phase inconsistency.Simulations were carried out to demonstrate the performance of the proposed scheme under varied circumstances.The conclusions are drawn that the proposal is able to modify the phase error and direction finding error of classic interferometer under deep-submergence radome model.
