Abstract

　互いに異なる符号でスペクトラム拡散された複数の超音波を第１および第２の受波器で受信し、第１および第２の受信信号を選択符号および非選択符号でそれぞれ逆拡散処理し、生成された選択逆拡散信号と非選択逆拡散信号との振幅比を求め、振幅比に基づいて閾値を決定し、非選択逆拡散信号から閾値以上の振幅を有する信号を抽出することにより干渉信号を生成し、干渉信号を対応する非選択符号で拡散処理した後、第１および第２の受信信号から除去することにより、干渉信号が除去された第１および第２の受信信号を生成し、干渉信号が除去された第１および第２の受信信号を選択符号でそれぞれ逆拡散することにより、干渉信号が除去された第１および第２の逆拡散信号を求め、第１および第２の逆拡散信号の第１および第２の受波器への到達時間から、選択された超音波の伝播距離および伝播方位を算出する超音波測定方法。
