摘　　要：航母在海洋航行时,为了使舰载机起飞和降落更安全,需要对航母姿态运动进行预报。艏前波法仅反映海浪本身的波动,没有考虑航母与海浪相互作用的情况。基于遭遇波的艏前波法,用航母遭遇海浪的观测序列替代海浪观测值作为ARMA模型的系统干扰,使得预报精度更准确。通过仿真分析,基于遭遇波的艏前波法结果与艏前波法结果对比,四级海况下,横摇运动预报4 s的误差不超过0.03°,预报8 s的误差不超过0.15°,纵摇运动预报4 s的误差不超过0.05°,预报8 s的误差不超过0.06°,结果表明了该方法的有效性。In order to keep carrier aircrafts taking off and landing safely, the carrier posture need to be predicted for carriers sailing on the sea. The bow wave method can only show the wave movements, without considering the interactions between the sea wave and aircraft carrier. This paper proposes an encounter-wave-based bow wave method, which uses the observation sequence of encounter wave in lieu of sea wave as the system interference of ARMA model to make the carrier posture prediction more accurate. Under 4 class sea condition, the two methods are discussed and compared. The simulation results verify the effectiveness of the proposed method. The error of pitching movement with 4 s predictions is less than 0.03°, and the error with 8 s predictions is less than 0.15°. The errors of rolling movement with 4 s and 8 s predictions are less than 0.05° and 0.06°, respectively.
