摘要:

干涉式测向机存在着阵孔径大小和准确度之间的矛盾。为解决这一问题,提出了一种新型天线阵及基于该天线阵的测向方法。重点讨论了新方法测向准确度的改进和各种误差对测向结果的影响,及其解决方法。提出基于新天线阵的补偿方法,理论上可以完全消除整个测向机的系统误差。通过Matlab软件中的仿真,证明了新方法的优势和可行性。

Abstract:

There is a contradiction between miniature aperture size and high accuracy in the interferometer Direction-finding machine. For solving this problem, a novel antenna array and Direction-finding algorithm based on it are proposed. The improvement of the new method and the effect of all kinds of errors are thoroughly analyzed and relevant solutions are discussed. A proposed relevant compensate method can counteract all system errors of the whole Direction-finding machine in theory. The advantage and feasibility of the new algorithm are demonstrated in the Matlab.
