    • One embodiment of the present invention provides a system that facilitates aligning a first signal with a second signal in a manner that optimizes a correlation between the first signal and the second signal. The system starts by receiving a set of signals, including the first signal and the second signal. The system then determines a correlation between the first signal and the second signal. Next, the system adjusts an alignment between the first signal and again determines a correlation between the first signal and the second signal. If the correlation is greater with the alignment adjustment, the system adjusts the alignment between the first signal and the second signal. This process of adjusting the alignment is repeated for different alignments to find an optimal alignment. Hence, the present invention operates effectively for signal sources which may be independently speeding up and slowing down with respect to each other while under surveillance.
    • 本发明的一个实施例提供了一种有助于以优化第一信号和第二信号之间的相关性的方式将第一信号与第二信号对准的系统。 系统通过接收包括第一信号和第二信号的一组信号来开始。 然后,系统确定第一信号和第二信号之间的相关性。 接下来,系统调整第一信号之间的对准,并再次确定第一信号和第二信号之间的相关性。 如果通过对准调整相关性较大,则系统调整第一信号和第二信号之间的对准。 对于不同的比对重复调整对准的这个过程以找到最佳比对。 因此,本发明对于信号源有效地进行操作,信号源可以在监视时相对于彼此独立地加速和减速。
