ABSTRACT:
By using the delay profile created by delay profile creating section102and the first threshold value330received from the first threshold value calculation105, the first threshold value timing detection section103selects only the earliest receive timing exceeding the first threshold value, from all the timing that the correlation value in the delay profile becomes a maximum. By using the receive timing and the second threshold value331received from the second threshold value calculation section107, reference timing calculation section106selects the reference timing required for calculating the receive timing for the incoming wave of the minimum propagation delay time. The timing delayed by previously set timing behind said reference timing is sent from receive timing calculation section108as the receive timing113of the incoming wave of the minimum propagation delay time.
