<p>PROBLEM TO BE SOLVED: To provide a frequency variation signal analyzer capable of analyzing a frequency variation signal with a high resolution.SOLUTION: The frequency variation signal analyzer includes: a signal acquisition unit 21 for acquiring an observation signal as a frequency variation signal; and an observation signal determination unit 22. The observation signal determination unit 22 previously stores a frequency variation signal model that is an equation expressing the frequency variation signal and includes one or more unknown parameters, determines the unknown parameter for allowing the frequency variation signal model to most agree with the observation signal by numerically searching for the unknown parameter, and determines, as an equation expressing the observation signal, the equation obtained by substituting the determined unknown parameter into the frequency variation signal model.</p> |
