Abstract:
1. A signal detection apparatus, comprising: a first multiplier that multiplies a first distributed signal provided by distribution of a received signal, by a first multiplication signal; a first integrator that integrates a result of the multiplication obtained in the first multiplier, in an integration period, and thereby calculates a first correlation value; a second multiplier that multiplies a second distributed signal provided by the distribution of the received signal, by a second multiplication signal; a second integrator that integrates a result of the multiplication obtained in the second multiplier, in the integration period, and thereby calculates a second correlation value; a delay section that delays the first distributed signal or the second distributed signal for time T a determination section that determines presence or absence of signals to be detected, respectively, based on a relative value between the first correlation value and the second correlation value, the signals to be detected being a periodic signal with a period T
