ABSTRACT:
The invention provides a detection object searching device which makes it possible to immediately know the direction of a mobile detection object such as a car by information presented on a display of a portable unit. The detection object searching device includes a portable operation unit and a body unit. The operation unit includes a transmission section for transmitting a search signal upon operation of a transmission button, a receiving section for receiving a direction indication information signal, an absolute direction detecting section for generating an absolute direction signal, a control section for generating direction indication information indicating the direction of the car based on the direction information signal and absolute direction signal, and a display section for displaying the direction indication information. The body unit includes a direction detection receiving section which searches the incoming direction of the search signal and generates an incoming direction signal, an absolute direction detecting section for generating an absolute direction signal, a control section for generating a direction information signal indicating the direction of the car with respect to the operation unit 1 from the incoming direction signal and absolute direction signal, and transmission section for transmitting a direction information signal.
