Abstract: The purpose of the present invention is to detect veering of a target, and to initiate individual particles in various directions by reflecting the speed of the target estimated at a veering point of the target, when the veering of the target is observed. In addition, the initiated particles are provided as filter input values of a model for analyzing target behaviors. Therefore, the convergence performance of filters used for a position estimating module for the target can be significantly improved by reflecting the veering of the target in the target behavior analysis, when the veering of the target exists.

Abstract: The present invention relates to a method for compensating a fluctuation error of a gun fire control system using a gun barrel image. A gun barrel camera takes a picture of a fluctuation component of which platform fluctuation caused by vessel fluctuation affects a gun barrel of the gun fire control system to analyze it. A gyroscope sensor detects the platform fluctuation caused by the vessel fluctuation to convert it into a platform fluctuation component in a direction of the gun barrel. Then, the analyzed fluctuation component of the gun barrel and the converted platform fluctuation component of the gun barrel direction are compared to detect a periodical fluctuation error component which can be provided in the whole gun fire control system. Also, in a case where a time delay is contained in the detected fluctuation error component, a magnitude of the delayed time between the gyroscope sensor and the gun of a warship is calculated and compensated.
