高概率宽带相位干涉仪测向解模糊算法

摘要

Wide-band phase interferometer is adopted by the new generation of fighting aircraft for high-precision direction finding. Based on the normal solving ambiguity algorithm of phase interferometer, a new method of Total-Baseline-Min-RMSE in weighted projection space is proposed which significantly improves the probability of solving ambiguity, and expands the re-striction of phase interferometer’s application in airborne environment. Theoretical analysis and simulation experiment demonstrate the advantage of this method.%先进作战飞机电子战系统采用宽带相位干涉仪对辐射源进行高精度方位测量。在相位干涉仪测向系统的常规解模糊算法基础之上，提出了一种基于加权投影空间全基线均方差最小的解算方法。理论分析和仿真计算表明，该方法可大幅度提升相位干涉仪测向的解模糊概率，拓宽了机载宽带相位干涉仪的应用条件。
