摘要： A measurement apparatus outputs from a first antenna pair transmission signals (St11) and (St12) whose phase difference (Δφ1) changes over time. A target object simultaneously receives the transmission signals (St11) and (St12) from a target-side antenna and returns to the measurement apparatus information (Dφ) according to the positional relationship between the target object and the measurement apparatus determined from a reception signal (Sr1). The measurement apparatus outputs from a second antenna pair transmission signals (St21) and (St22) whose phase difference (Δφ2) changes over time. The target object simultaneously receives the transmission signals (St21) and (St22) from the target-side antenna and returns to the measurement apparatus the information (Dφ) corresponding to the positional relationship between the target object and the measurement apparatus determined from a reception signal (Sr2). The measurement apparatus identifies a direction (θ) of the target object on the basis of these two pieces of information (Dφ).
