Target detection device and target detection method.

Abstract

A target detection device (1) comprising a transmit signal generator (103), a transmit array (10), a switch (104), and a controller (101) is disclosed. The transmit signal generator (103) is configured to generate a transmit signal. The transmit array (10), comprising a plurality of transmit elements (11), is configured to convert the transmit signal into a transmit wave. The transmit array (10) has at least one initial transmit element (11a) and one final transmit element (11b). The switch (104) is configured to provide the transmit signal to the plurality of transmit elements (11) sequentially from the initial transmit element (11a) to the final transmit element (11b). The controller (101) is configured to control a sweep time of the switch (104).The sweep time is the time from the provision of the transmission signal to the initial transmission element to the provision of the transmission signal to the final transmission element.
