摘要： A WiGig wireless device partially performs a masking processing on a preamble of a transmission signal frame and generates a repetition pattern of the same pulse capable of being used in a correlation detection of a sensor. That is, a repetition pattern of a Golay code is output by intermittently performing the masking processing on the Golay code sequence. The sensor performs the correlation detection using a pulse compression technology, thereby detecting the antenna radiation pattern even in an environment where a reflected wave is generated, by separating the direct wave and the reflected wave.

摘要： A pulse signal is produced in a pulse generating section, and repetitively transmitted from an antenna at constant time intervals. A reception signal, received through an antenna and including a reflective wave from an object, is amplified and gain-adjusted. Thereafter, a distance detecting section detects a reception pulse of the reflected wave, and calculates the distance to the object. The variable attenuator attenuates the reception signal by a gain adjusted in accordance with a gain control signal. The gain of the variable attenuator is controlled so as to be maximum immediately after the pulse signal is transmitted, and to be reduced with elapse of time. Based on a gain adjustment timing signal, a gain adjustment timing when the attenuation amount is changed is made different for each transmission of the pulse signal.

摘要： The disclosed technique includes transmitting a signal intermittently according to a transmission cycle having a predetermined transmission period and a non-transmission period; receiving the signal reflected from a target with reception antennas; and detecting the target from the reflected signal. A high-frequency transmission signal attenuated during the transmission period and a receipt signal received during the non-transmission period are combined together. A correlation value between a reference transmission signal and the receipt signal in the combined signal is calculated, and the amount of phase shift in an arbitrarily selected reception antenna is calculated from the correlation value of a reference reception antenna, and the correlation values of the other reception antennas. The phase component of the correlation value of the arbitrarily selected reception antenna is corrected on the basis of the amount of phase shift.
