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.

Abstract: PURPOSE: A method and a device for processing target information in a gun-fire control system are provided to stably perform trace by forcibly changing the parameter of a Kalman filter or discarding measurement by determining discontinuous change. CONSTITUTION: A method for processing target information in a gun-fire control system is as follows. Measurement on target information is received, and it is determined whether discontinuous change of a spike shape has occurred on the target information(S10). If spike has occurred on the target information, it is determined whether discontinuous change of a step type has occurred on the target information(S14). If the spike-shaped discontinuous change occurs on the target information but the step-shaped discontinuous change dose not occur, then the measurement on target information is processed as a predicted value in the previous cycle(S22,S23). If the step-shaped discontinuous change occurs on the target information, the predicted value on the target information is processed as the measurement on target information(S21).
