Abstract
In this signal detection device (), a delaying unit () delays a first distributed signal or a second distributed signal distributed from a received signal for a period of time of Tto form a first multiplication signal, and delays the one for a period of time of T(T>T) to form a second multiplication signal. An integrator () calculates a first correlation value by integrating the result of multiplying the first distributed signal and the first multiplication signal. An integrator () calculates a second correlation value by integrating the result of multiplying the second distributed signal and the second multiplication signal. An evaluation unit () evaluates whether the signal to be detected, which is a periodic signal with a period of Tor a periodic signal with a period of T, exists or not, on the basis of the first correlation value and the second correlation value.
