| Abstract(in English) | Recently, Doppler radar has been used in various applications. It can estimate velocity of a target by using Doppler effect relative to reflecting of radio wave. Doppler radar can be applied for human activity classification. By analyzing frequency spectral pattern of echo waves reflected from human's arms and legs, we can classify various human activities. In addition, two frequency continuous wave (CW) method is well-known as a localization method that can estimate the position of a target by using phase information of Doppler signal extracted from echo waves. However, if plural targets exist in observation area, since each echo is received as a synthetic wave, we cannot separate each phase component. Thus, we cannot estimate each position coordinate accurately. In this report, we propose bistatic three frequency CW method that can estimate the positions of plural human beings accurately by spatial steering using Doppler frequency. By analyzing the synthetic wave of echo reflected from each human body part, we classify various human activities and estimate the position of human being simultaneously. |
