A radio monitoring method which can estimate the position of an objective radio wave source with a high degree of accuracy by taking an influence of the geography or objects on the ground into consideration. According to the method, radio wave hologram observation is performed at individual sensor stations to acquire radio wave reconstructed images, and the reconstructed images are compared with results of a computer simulation prepared in advance to determine a candidate position of the radio wave source. The computer simulation is repeated while the position of the radio wave source is successively varied in the proximity of the candidate position to finally determine the position of the radio wave source. Map information is used in the computer simulation to simulate radio wave propagation with an influence of the geography and objects on the ground into consideration. After the position of the radio wave source is determined, an observation point may be set to or in the proximity of the position, and a radio wave photograph observation car may be moved to the observation point to acquire a radio wave photograph through radio wave hologram observation. The radio wave source can be identified from an image on the radio wave photograph.
