Abstract: A method includes, in accordance with some implementations, sending, a measurement station, a trigger frame to a signal source station, where the trigger frame carries pilot format information, and the pilot format information is used to indicate a sending time point of a signal frame triggered by the trigger frame, a quantity of times for sending the signal frame, and a transmission mode of pilot information in the signal frame. The measurement station receives an illumination frame from the signal source station, where the illumination frame is the signal frame triggered by the trigger frame. The measurement station analyzes pilot information in the illumination frame to obtain sensing information in the illumination frame, where the sensing information is used to indicate physical information of an object surrounding the signal source station and the measurement station.
