<p>PROBLEM TO BE SOLVED: To provide a target monitoring method or the like, capable of accurately monitoring a moving target. SOLUTION: Concerning this target monitoring method, with which the reflection intensity of a transmitted signal at a certain position is defined as a reflected signal and the presence/absence of a target is determined and monitored on the basis of this reflected signal, and on the basis of the total sum of reflection intensities shown by plural reflected signals at the same position as different time, a processing means 25 determines the presence/absence of the target at that position and transmits a supervisory signal based on that determination.</p> |
