Detection device and detection method

Abstract

Provided are a detection device and a detection method capable of accurately detecting a detection target. 【Solution means】The detection device 2 has a received signal processing unit 25 that detects a living body H based on the received signal x. The received signal processing unit 25 includes a time series signal acquisition unit 270 that acquires time series signals x at a plurality of detection distances r from the received signal x, a first time series signal acquisition unit 272 that acquires a first time series signal x from among the plurality of time series signals x, a regression coefficient acquisition unit 273 that acquires a regression coefficient A by performing regression on the plurality of time series signals x using the first time series signal x, a noise acquisition unit 274 that acquires an estimated noise signal Sn based on the regression coefficient A and the first time series signal x, a second time series signal acquisition unit 275 that corrects the plurality of time series signals x using the estimated noise signal Sn to obtain a second time series signal y, and a determination unit 276 that determines the presence or absence of the living body H within the detection area using the second time series signal y. r to obtain a time series signal acquisition unit 270, and a plurality of time series signals x r from among the first time series signal x R0 to obtain a first time series signal acquisition unit 272, and a plurality of time series signals x r for the first time series signal x R0 to obtain a regression coefficient acquisition unit 273 that obtains a regression coefficient A by performing regression, a noise acquisition unit 274 that obtains an estimated noise signal Sn based on the regression coefficient A and the first time series signal x, and a plurality of time series signals x R0 to obtain an estimated noise signal Sn, and a second time series signal acquisition unit 275 that corrects the plurality of time series signals x using the estimated noise signal Sn to obtain a second time series signal y r to obtain a second time series signal acquisition unit 275, and a second time series signal y r to obtain a second time series signal acquisition unit 275, and a second time series signal y r using a determination unit 276 that determines the presence or absence of the living body H within the detection area, and having.
