摘要：
In an obstacle detection system, a wave transmitted by a transmitting element and received by receiving elements as a receiving wave includes extraneous waves, which are reflection waves from other than an obstacle, and obstacle reflection waves from an obstacle. It is determined that, an obstacle is present, if the reflection waves are detected as having an amplitude (voltage) greater than a threshold level and a reception time difference between time points at which the amplitude exceeds threshold level at the receiving elements is less than a predetermined time.
