基于圆柱体基线的测向误差分析

摘要

The direction finding error in the cylinder antenna model was studied and the simple method of fast comparison error was summarized based on error formula of heading angle and pitching angle. According to the simulation results, the antenna position influences on direction finding error were analyzed. Moreover, the method of fast comparison error was verified. The results show that projection area of antenna has an inverse relationship with finding direction error. The angular accuracy of cylinder baseline is better than that of planar baseline.%推导圆柱体基线下的测向误差表达式，并根据误差公式提出快速比较航向角和俯仰角误差的简便方法。根据测向误差公式仿真分析天线位置对测向误差的影响，并且验证快速比较误差方法的有效性。研究结果表明：天线投影面积与误差呈反比，圆柱体基线的测角精度比平面基线的更优。
