We have proposed an intruder detection method by using Multiple Input Multiple Output (MIMO) channel. Although the channel capacity on the MIMO transmission is severely degraded in time variant channels, we can take advantage of this feature MIMO Sensor applications. We have already proposed the channel estimation method using arbitrary amplitude and phase modulation schemes for MIMO sensor. Moreover, the basic performance by the proposed CSI estimation method is verified when considering the intruder detection by MIMO sensor. In this paper, we study try to estimation of e behavior patterns by MIMO sensor with using time correlation with a narrow-band FSK signal. We evaluated the variation of the time correlation with people behavior by experiment. It is shown that motion behavior patterns such as standing up, seating and rotation can be estimated by the time correlation function via the experimental results.
