This radar module is provided with: a transmission antenna; a reception antenna; a signal source for generating a transmission signal; a transmission unit for transmitting a transmission signal towards a target object through the transmission antenna; a reception unit for receiving, through the reception antenna, a reflected signal produced by reflection of the transmission signal from the target object; a signal processing unit for performing signal processing on the basis of a reception signal outputted by the reception unit; and an external interface for outputting information obtained by the signal processing unit. The signal processing unit calculates an average value and a variance value of the received power of the reception signal, and uses the calculated average value and variance value to identify the target object.
