摘要：
A signal detection apparatus includes: a unit configured to select a particular detection target signal from among plural candidates of detection target signals; a unit configured to calculate a cyclic autocorrelation value at a center coordinate point specified by at least a cyclic parameter and a shift parameter of the particular detection target signal; a unit configured to calculate a cyclic autocorrelation value of each of (L-1) coordinate points belonging to a common area that is used commonly for different detection target signals; a unit configured to calculate a test statistic of the particular detection target signal; and a unit configured to determine presence or absence of the particular detection target signal according to a comparison result between the test statistic and a threshold, wherein the test statistic is calculated by using the cyclic autocorrelation value in each of the (L-1) coordinate points belonging to the common area.
