MOVING OBSTACLE DECIDING APPARATUS
First Claim
1. A moving obstacle deciding apparatus comprising:
- a search signal transmitting and receiving section for transmitting a search signal, and for receiving the search signal reflected from a search target as a detection signal;
a decision reference value calculating section for dividing a range of a transmission period of the search signal into a prescribed number of divisions, and for calculating a decision reference value based on an integral value of the detection signal occurring in each of the divisions; and
a deciding section for making a decision as to whether the search target is a moving obstacle or not in accordance with a compared result of a difference value between the decision reference values obtained in time-series searches by the decision reference value calculating section with a prescribed threshold.

Abstract
A moving obstacle deciding apparatus includes a search signal transmitting and receiving section 1 for transmitting a search signal, and for receiving the search signal reflected from a search target as a detection signal; a decision reference value calculating section 6 for calculating a decision reference value based on the detection signal received by the search signal transmitting and receiving section 1; and a moving obstacle deciding section 10 for making a decision as to whether the search target is a moving obstacle or not in accordance with a compared result of a difference value between decision reference values obtained by the decision reference value calculating section 6 in time-series searches with a prescribed threshold.
