Abstract: There is provided a moving-body-abnormal-nearing detection system capable of determining whether abnormal nearing between moving bodies will occur in a short processing time. A projection matrix calculation means 71 calculates a first projection matrix indicating mapping from a 3D space onto a 2D plane based on period information of a first moving body and period information of a second moving body. An abnormal nearing determination means 72 maps the period information of the first moving body to a line segment in the 2D plane by use of the first projection matrix. It then determines whether abnormal nearing between the first moving body and the second moving body will occur by determining how a circle whose center is a passage position of the second moving body and whose radius takes a threshold as a determination standard as to whether abnormal nearing will occur crosses with the line segment.

Abstract: A learning model is trained so that a signal state can be estimated with high accuracy even in a case where a constellation on a complex plane is rotated. A learning apparatus (1) includes: an acquisition section (11) that acquires a constellation of a known state optical signal transmitted through optical fiber; a generation section (12) that generates a corrected constellation obtained by rotating the constellation on a complex plane; and a learning section (13) that uses the constellation and the corrected constellation to train a learning model.

Abstract: A peripheral aircraft selection means maps a region in a 3D space defined by a start point of period information of the aircraft of interest, a point having the coordinate values of passage position coordinates at an end point of the period information and a lower limit arrival time, and a point having the coordinate values of passage position coordinates at the end point of the period information and an upper limit arrival time onto a 2D plane by use of a first projection matrix. The peripheral aircraft selection means then selects a peripheral aircraft which can abnormally near to the aircraft of interest by determining how the resultant region crosses with a circle whose center is a passage position of the peripheral aircraft and whose radius is a determination standard threshold as to whether abnormal nearing will occur.
