Abstract

The object is to provide a target detection device and a target detection method capable of detecting a target using a simple configuration. The solution is that the target detection device (1) includes: a first transmission signal generation unit (111) configured to generate a first transmission signal; a second transmission signal generation unit (121) configured to generate a second transmission signal; a transmission wave array (10) having a plurality of transmission wave elements (10a) configured to convert the first transmission signal into a transmission wave; a first signal switching unit (113) configured to supply the first transmission signal to one of the transmission wave elements (10a) in the transmission wave array (10); a second signal switching unit (123) configured to supply the second transmission signal to one of the transmission wave elements (10a) in the transmission wave array (10); and a control unit (101) configured to control the first signal switching unit (113) to switch the transmission wave element (10a) supplied with the first transmission signal from element n to element n+1, and the second signal switching unit (123) to switch the transmission wave element supplied with the second transmission signal from element m to element m+1.
