摘　　要：针对AUV抵近目标前沿海区执行任务而可能被海岸声呐探测,从而影响AUV隐蔽突防的问题。通过构建海岸声呐对AUV探测距离预估模型、海岸声呐对目标探测概率模型,从探测距离、概率2个方面,分析海岸声呐对AUV隐蔽突防的影响,给出了声呐探测距离与航速、海况对应变化关系及海岸声呐对AUV探测概率拟合曲线。在获取AUV航速、海况等级、海岸声呐布设位置等关键信息后,可预报声呐对AUV的探测距离及不同区域的探测概率。最后基于典型AUV任务态势设定了AUV隐蔽突防威胁等级表,提出AUV在不同情况下的隐蔽突防策略。Aiming at the problem that different ocean current environments will produce different degrees of errors in the position of AUV navigation ships,by constructing an AUV movement model in an ocean current environment,based on the AUV navigation ship position distance error and the ship position error evaluation index in the ocean current area,the impact of the ocean current environment on the AUV navigation error is analyzed.The results show that when the ocean current flow direction or velocity reaches a certain value,the influence on the distance and azimuth error of the AUV navigating ship's position increases abruptly.Compared with ocean current flow direction,ocean current velocity has a more direct influence on AUV ship position error.Under certain circumstances,ocean currents of different directions and sizes will have a consistent effect on the position error of AUV navigation.By setting the AUV position error threshold,the direction and size of the current that can cause the AUV to reach the error threshold are reversed,which can provide auxiliary decision-making for AUV route planning.Avoid the sea area with corresponding ocean currents,and improve the AUV's ability to accurately deliver weapons,equipment and materials over long distances.
