Sensing technology using radio wave has been attracting attention for various applications such as office/home security and surveillance. Classification of human motion has been extensively studied in these applications. They often utilize micro-Doppler signature, or Doppler frequency signature occurred by human motion. In this paper, 4 type of range-Doppler signatures in human motion at a certain range are studied, and difference of the motions is confirmed experimentally. Moreover, extraction technique for range-Doppler signature with several moving humans are studied. Experimental results show that we can easily suppress the undesired extract the desired target responses and target response by using range-Doppler filtering scheme.
