To provide a correlation function measuring method which can correct a correlation vector with high accuracy. There are provided first signal processing means 18a to 22a for processing a first monitored signal to give a first spectrum, second signal processing means 18b to 22b for processing a second monitored signal to give a second spectrum, correction value computing means 26 for inputting correction signals to the first signal processing means and the second signal processing means to give correction values corresponding to respective frequencies, based on the spectrum given by the first signal processing means and the spectrum given by the second signal processing means, and correlation function computing means 30 for giving a correlation function between the first spectrum and the second spectrum by using correction values given by the correction value computing means.
A correlation function measuring method in which a first monitored signal is processed by a first signal processing means to give a first spectrum, a second monitored signal is processed by a second signal processing means to give a second spectrum, and a correlation function between the first spectrum and the second spectrum is measured, the method comprising the steps of:
A correlation function measuring apparatus comprising:
