However, in the case of the above technical examples, interference due to mixing of multiple waves and complex waves such as band noise is considered. There has been a problem that it is extremely difficult to limit the interference wave to one wave. It is difficult to determine these only by detecting various triggers (such as a certain level or more of a strong electric field level). Also, in order to identify the interfering signal, a measuring instrument was installed on site, and it was difficult to collect data unless a human continued to measure on site until the occurrence of the interfering signal. It takes a lot of wasted time and labor, the workability is very poor, the data collection of spectrum etc. can only be kept for a short time, the work of clearing the data at any time is necessary, There is a problem that the amount of information of the acquired data becomes scarce because a human has to manually perform data collection such as media.
