Signal detection circuit and detection method using the same

Abstract

Provided are a signal detection circuit and a detection method using the signal detection circuit. The signal detection circuit includes a reconfigurable intelligent surface, a multiple input/output circuit connected to the reconfigurable intelligent surface, a magnitude detection circuit connected to the multiple input/output circuit, and a processor connected to the magnitude detection circuit, wherein the reconfigurable intelligent surface includes a sampling area arranged to intersect in a first direction and a second direction, the multiple input/output circuit is configured to receive and process a signal from the sampling area, the magnitude detection circuit is configured to receive the signal from the multiple input/output circuit and detect a magnitude of the received signal, and the processor is configured to identify an incidence direction of the signal based on a detection result of the magnitude detection circuit.

Dependencies are inferred from the claim text.
