Abstract
A signal detection apparatusfor determining whether a detection target signal is included in a received radio signal, includes: a waveform feature amount calculation unitconfigured to calculate a waveform feature amount Rrepresenting a waveform feature; a test statistic calculation unitconfigured to calculate test statistic Zof each detection target signal by using the waveform feature amount; and a signal decision unitconfigured to determine presence or absence of each detection target signal by comparing the test statistic Zof each detection target signal with a threshold Γ, wherein, under a condition where a specific detection target signal is removed, the test statistic calculation unit calculates a test statistic for a detection target signal which is not removed, and the signal decision unit determines presence or absence of the detection target signal by comparing the calculated test statistic with the threshold.
