OBSERVATION INFORMATION PROCESSING DEVICE, OBSERVATION INFORMATION PROCESSING METHOD, AND OBSERVATION INFORMATION PROCESSING PROGRAM

摘要

The present invention provides an observation information processing device, observation information processing method, and observation information processing program for accurately estimating the two-dimensional or three-dimensional speed of an object under observation on the basis of the one-dimensional speed of the object under observation along a sensor line-of-sight direction. An observation information processing device (10) having a speed estimation unit (30) for estimating a two-dimensional or three-dimensional speed on the basis of a one-dimensional speed of an object under observation along a sensor line-of-sight direction, which has been acquired by a weather sensor (S), through the application of linear inverse problem solving to a linear equation using a coordinate transformation matrix and a projection matrix to associate a first vector including, as elements, all speed vectors at each grid point of a Cartesian coordinate system; a second vector including, as elements, all regions containing the first vector of the speed vectors at each grid point of a polar coordinate system; and a third vector including, as elements, the speed measurement values of all the areas containing the first vector in the sensor line-of-sight direction.
