摘　　要：为了探讨舰艇摇摆对小口径舰炮射击精度的影响,利用线性系统理论,推导出舰艇摇摆运动的幅频和相频传递函数,通过波谱密度函数构建海浪运动模型,驱动舰艇的摇摆运动,在此基础上建立了舰炮对空射击的误差传递模型。选取典型海情对舰艇摇摆造成的射击误差进行了仿真研究,结果表明,海况越差时,舰艇摇摆越剧烈,引起的摇摆误差越高,舰炮射击误差也越大,并且高低角方向的射击误差要远高于方位角方向的射击误差。To verify the influence of warship rocking on firing accuracy of small caliber naval gun, the amplitude-frequency and phase-frequency transfer function of warship rocking model was firstly calculated by use of linear system theory. The wave model was established subsequently by means of spectral density function to drive the motion of warship rocking, and on that basis, the anti-air firing error transfer model of the naval gun was built up. Simulation results indicated that under the worse sea condition, the warship rocking is more violent, and the rocking error is higher as well as the naval gun firing error is also bigger. In addition, the naval gun pitch angle firing error is much higher than the azimuth angle firing error.
