摘要
文中充分利用二维多波束输出的特点,首次将曲面拟合技术应用于二维多波束测向领域,提出一种高精度的二维多波束测向方法,即基于曲面拟合的二维多波束测向算法。文中不仅推导出该算法的数学表达式,还总结出影响该算法测向精度的三个主要因素;最后通过仿真实验分析了三个因素对测向精度的影响。结果表明该方法具有很高的稳健性及较好的测向精度。
A highly accurate multi-beam direction-finding algorithm was proposed based on curved surface fitting by making the best use of the feature of 2-D multi-beam output.This algorithm applied surface fitting to 2-D multi-beam direction-finding for the first time.The mathematical expression of this algorithm was deduced and three major factors of direction-finding influence were also summarized.At last,the influence of these three factors on direction-finding accuracy was analyzed by simulation experiments.The result of simulation experiment analysis shows that this method has higher steadiness and better direction-finding accuracy.
