| Abstract: | According to the characteristic of echo signals of high frequency ground wave radar, this paper constructed virtual DOA matrix using one-dimensional narrow band signal. Making full use of redundancy information, array self-calibration of high-resolution was realized with the method of resolving equations for the two rows linear array of high frequency ground wave radar. On the end of this paper, in spite of low SNR echoes and short data series for analyzing, experiments show the validity of this method and the applicability for practical projects. |
