Abstract
This disclosure provides a method of setting a threshold according to a level of an echo signal containing an unused component. The echo signal is generated by transmitting and receiving a radio wave with an antenna while the antenna revolves. The method includes acquiring levels of the echo signals at every predetermined distance interval and updating a threshold set for an observing position based on the level of the echo signal at the observing position, the threshold set for the observing position, and a threshold set for a position closer to the antenna than the observing position by the predetermined distance on the same sweep.
