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.
