Abstract

A target trajectory estimating device includes: an orientation information reading unit (41) to read orientation information indicating an orientation measurement value obtained by each of a plurality of orientation sensors (10) that has received an incoming radio wave from an object target (100) and orientation measurement error information indicating an orientation measurement error accompanying or uniformly set to the orientation measurement value indicated by the orientation information; a time domain dividing unit (43) to divide time when each of the plurality of orientation sensors (10) has observed the object target (100) into a plurality of time domains in time-series order, and divide the orientation information read by the orientation information reading unit (41) for each of the divided time domains; an abnormal value determining unit (44) to perform, for each of the time domains obtained by the time domain dividing unit (43), determination of whether or not an orientation measurement value indicates an abnormal value on the basis of whether a position indicated by an orientation measurement value indicated by each of the plurality of pieces of orientation information present in the plurality of time domains is concentrated at one point or is concentrated around a state vector including a position and a speed, reset an orientation measurement error accompanying the orientation measurement value determined to be an abnormal value to a setting for lowering reliability with respect to trajectory estimation of the orientation measurement value, and reset an orientation measurement error accompanying the orientation measurement value determined not to be an abnormal value without changing reliability for trajectory estimation of the orientation measurement value; a positioning processing unit (45) to estimate, for each of time domains divided by the time domain dividing unit (43), a positioning value for the object target (100) in each of the time domains using the orientation measurement value indicated by the plurality of pieces of orientation information present in the plurality of time domains and a reset orientation measurement error accompanying the orientation measurement value; and an output unit (46) to output object trajectory information indicating a trajectory of the object target (100) by connecting, in time-series order, the positioning values for each of the time domains estimated by the positioning processing unit (45).
