A WiGig wireless device (20) partially masks the preamble of a transmit signal frame and generates a repeating pattern of the same pulses which can be used in correlation detection on the sensor (10) side. That is, a Golay code sequence is intermittently masked, and a repeating pattern of Golay codes is output. The sensor (10) uses pulse compression to perform correlation detection so that even in an environment where reflected waves would be generated, the sensor (10) is able to separate direct waves and reflected waves and detect an antenna radiation pattern. |
