Summary:The invention discloses a short wave direction finding method based on polarization correction, which is used for a short wave antenna array, the antenna array is formed by arranging M horizontally polarized antenna array elements according to a circular array, M is greater than or equal to 3, and the interval of the antenna array elements is theta (determined according to the antenna beam width). According to a plurality of steps, a scanning angle-correlation coefficient curve is obtained, the scanning angle corresponding to the point with the maximum correlation coefficient is the direction of arrival, and the direction finding of the frequency point is ended. According to the short wave direction finding method based on polarization correction, interference of polarization components on direction finding is eliminated by correcting the polarization components of the incoming waves. Compared with an existing short wave direction finding algorithm, the method has the remarkable advantages that the method has
