Abstract：Naval guns can effectively deter enemy ships from intruding into territorial waters and adjacent areas by issuing warning or interdiction fire.To effectively deter intrusion,it is necessary to fire some distances ahead of the enemy ship's course.To avoid escalating the situation,the impact point of the shell must be accurately calculated.This paper presents a general method for virtual point firing based on distance and azimuth,taking into account the time required for the gun to prepare and the flight time of the shell.It analyzes the effects of key parameters such as speed and course on the accuracy of the shot,and finally draws a disper-sion diagram of the impact point under typical conditions,providing decision-making support for commanders.
