Abstract
A detection device for communicating with an external device includes a smart antenna, a storage device, and a processor. The smart antenna is capable of switching between a plurality of antenna modes. In each of the antenna modes, the smart antenna transmits a test datum and receives a feedback datum according to the test datum, the processor performs a time reversal algorithm to the feedback datum so as to obtain a time reversal datum, the processor calculates an indicator according to the feedback datum and the time reversal datum, and the storage device stores the feedback datum, the time reversal datum, and the indicator. The processor compares all of the indicators with each other and controls the smart antenna to select the final mode of the antenna modes according to a comparison between all of the indicators.
