An intruder detection method by using time variant Multiple Input Multiple Output (MIMO) channels has been proposed (MIMO sensor). In this letter, the detection performance using eigenvectors, which are obtained by singular value decomposition for MIMO channel matrix, is evaluated in actual indoor propagation environment. Moreover, a new diversity method using multiple eigenvectors is proposed to enhance the performance of the intruder detection using eigenvectors. Scenarios that are effective for 1st and 2nd eigenvectors is verified and the effectiveness using multiple eigenvectors is shown compared to the MIMO sensor using the channel matrix.
