The wide-band direction finding is one of the key projects in communication and signal processing. It has important applications in many fields.This paper derives the cost function of wide-band deterministic maximum likelihood direction finding algorithm under the assumption of Gaussian noise and deterministic source,and then the function is optimized by alternating projection algorithm.The direction of arrival is estimated without preprocessing of array data and so the algorithm eliminates the effect of pre-estimate on the final estimation result. The algorithm is applied to uniform linear array and extensive simulation results prove the effectiveness of the algorithm. It has a broad application in wide-band direction finding.

宽带测向是通信与信号处理研究领域中的重要课题,在诸多领域都有重要应用.在高斯噪声和确定性信号假定下,文中推导出宽带确定性最大似然测向算法的代价函数,然后应用交替投影算法进行优化,即可得到波达方向估计值.与相干信号子空间方法相比,该算法不需要对波达方向进行预估计,因此就避免了预估计误差对最终估计结果的影响.把该算法应用到均匀线阵上,仿真实验结果证明了该算法的有效性,在宽带测向方面具有很好的应用前景.
