Three Median Relations of Target Azimuth in one Dimensional Equidistant Double Array

Abstract

 Before this paper, the authors have obtained the tangent median relation by using the trigonometric function equation. In this paper, on the basis of the linear positioning solution of one-dimensional equidistant double-base linear array, by proper approximate treatment of the strict solution, and by using the direction finding solution of single base path difference, the sinusoidal median relation of azimuth angle at three stations of the linear array is obtained. By using the sinusoidal median relation, the arithmetic mean solution of azimuth angle at three stations is obtained. All these results reveal the intrinsic correlation between the azimuth angles of one-dimensional linear array.
