【摘要】 针对高频地波雷达回波信号的特点,利用一维远场窄带信号构建虚拟DOA矩阵。充分利用冗余信息,联立方程组求解对双排线阵的高频地波雷达进行高分辨阵列自校正。最后实验证明,在低信噪比、短数据情况下,该方法具有可行性和工程应用性。更多还原

【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.更多还原
