摘要 为了避免相位干涉仪测向技术中存在的模糊问题,提高宽带信号时延估计的测量精度,把互相关和多重信号分类算法结合,引入到频域时延估计领域,研究了互相关MUSIC算法。利用互相关技术可消除非相关噪声,检测概率增加,减小了运算量。仿真结果表明,该算法具有较高的估计精度,较强的抗噪性和较强的鲁棒性,适用于电子对抗领域中的时延估计。 For avoiding fuzzy in the direction-finding technology of phase interferometer, and for improving measuring precision of wideband signal delay estimation, the combination of cross-correlation function and multiple signal classification（MUSIC） algorithm was introduced to the field of time delay estimation（TDE） in frequency domain. A MUSIC based on cross-correlation function high precision TDE algorithm was researched. The irrelevant noise can be completely eliminated by the cross-correlation method in theory , and computation is reduced, the detection probability increases. The simulation results show that the algorithm is featured with high precision and robustness, fitting for TDE in electronic countermeasure.
