【摘要】 把Toeplitz技术应用于舰载环境的均匀圆阵,首先通过预处理技术把阵元空间的均匀圆阵转换为模式空间的均匀线阵,然后对模式空间中均匀线阵的相关矩阵进行Toeplitz化处理,再利用ESB算法进行波束形成.理论分析表明该算法可得到较快的收敛速度,并可实现均匀圆阵的抗相干干扰,计算机仿真证实了方法的有效性.更多还原

【Abstract】 Toeplitz technique was applied to beamforming algorithm based on mode space for a shipborne uniform circular array. By utilizing preprocess technique this novel approach at first transforms the uniform circular array in element space into a virtual uniform linear array in mode space of which the manifold matrix is of Vandermonde structure. By means of Toeplitz technique this beamforming algorithm can rapidly converge and efficiently overcome the problem that the conventional beamforming algorithm for the uniform circular array can not work in the environment of coherent signals. Computer simulation results show that the method is effective.更多还原
