PROBLEM TO BE SOLVED: To provide a monitor system capable of optically observing a target object going around the earth from the ground, and estimating a feature, state, and kind of the target object even when altitude of the target object is equal to or more than a stationary orbit, and a monitor method using the monitor system.SOLUTION: Change of luminance of the target object is analyzed, and periodicity of the luminance is extracted. By performing matching with a catalog in which pieces of data related to candidates of the target object are recorded, a feature of the target object is estimated. Even when resolution obtained by optical observation is low, as long as the luminance information can be acquired, the feature and state of the target object can be estimated. |
