摘　　要：分析了观察平台晃动条件下的两种定向误差 ,分析结果表明 :由平台坐标系的平移所引起的定向误差可以忽略 ,但由其旋转所引起的误差是必须加以考虑的。然后 ,应用声强向量作为观测量 ,在晃动观测平台上对舰船目标进行了被动跟踪和尺度估计。Two kinds of bearing errors under the condition of a sway observation platform are analyzed in this paper. And the analysis results obtained indicate that the errors caused by the translation of platform coordinates can be ignored but the ones caused by their rotation must be considerde. Then, the passive tracking of a ship are made and its longitudinal size is estimated with the help of an acoustic intensity vector method. The simulation results obtained have proved the effectiveness of this method.
