摘要
随着对测向定位性能需求的不断提高,越来越复杂的干涉仪测向系统被提出,针对传统一维、二维正交基线构成的简单干涉仪的误差分析方法不再适用。基于卡尔曼滤波理论和阵元相位差模型,提出任意基线干涉仪定位误差分析算法。该算法充分考虑相位差相关的因素,可以在超定情况下得到任意基线干涉仪的测向定位误差分析模型,使干涉仪测向定位误差分析更加真实、准确。最后,通过计算机仿真验证所提出方法的有效性。
More and more complicated interferometer bearing systems are designed to satisfy the higher performance of passive positioning.The current positioning error analysis methods for the simple interferometers,such as 1 D and 2 D interferometers,are no longer applicable.Therefore,the novel analysis algorithm of positioning error for arbitrary interferometer is proposed by utilizing Kalman filtering theory and the element-based phase difference.In the proposed method,the influence of the phase difference correlation is considered earnestly;consequently the positioning error analysis for arbitrary interferometer can be obtained in the overdetermined condition.Finally,simulations are conducted for verification.
