Target object detection device and method of displaying echo data in the target object detection device

摘要

A target object detection device (100) is provided. The device (100) includes a signal processor (108), a display unit (103), and a controller (101). The signal processor (108) receives a reception signal generated based on an echo of an ultrasonic wave from a target object and generates echo data corresponding to a distance from a transmission source (110) of the ultrasonic wave to the target object every time the ultrasonic wave is transmitted. The display unit (103) has a display screen (103a) with a first side (103b) and a second side (103c) that is turnable around an axis perpendicular to the display screen (103a), and displays an image on the display screen (103a) based on the echo data. The controller (101) sets a range with respect to time at which the ultrasonic wave is transmitted, and outputs the echo data corresponding to the ultrasonic wave within the time range according to a turning state of the display screen (103a).
