Original Abstract Submitted
a sensor includes a complex-transfer-function calculator that calculates a complex transfer function from received signals, a reflection-coefficient calculator that calculates a reflection coefficient using a complex transfer function when an object to be detected is arranged at one of l positions and an ideal complex transfer function which is a theoretical value for the position at which the object to be detected is arranged, various normalizers that calculate a normalized reflection coefficient by normalizing the reflection coefficient, a reflection-coefficient interpolator that calculates an interpolated reflection coefficient by interpolation calculation of the reflection coefficient using the normalized reflection coefficient for each coordinates used in position estimation of the object to be detected, and a position estimator that corrects the position estimation, using a steering vector and the interpolated reflection coefficient that are determined based on the position of each of the transmitting antenna elements and the receiving antenna elements.
