舰艇机动穿越深海会聚区对潜艇探测研究

深海会聚区效应是深海水声传播显著的特征，并为远距离潜艇探测提供了有效途径。首先分析了深海会聚区形成的原因和条件，然后根据海区会聚区的预报距离和宽度，构建了舰艇采用两次机动穿越会聚区测算被探测潜艇的位置和运动要素模型，最后通过算例分析舰艇两次穿越会聚区的方法和求解潜艇运动要素和位置的过程，分析结果验证了舰艇穿越会聚区对潜艇定位方法的可行性。

Study on the methods of submarine source localization with surface ships traversing in deep sea convergence zones

Deep sea convergence zones is one of the obvious characters of the underwater sound propagation in deep sea, and it may be an efficient way to detect submarines in a long distance. First, the thesis analyzed the causes and conditions of convergence zone in deep sea. Then, based on the forecast distance and extent of the convergence zone, using the method of the surface ships traversing the convergence zones twice, the thesis established the model to calculate the location and moving elements of the submarines which are detected. Finally, some analysis were given about the surface ships traverse procedure, the passive localization and motion element calculation of the submarine target.
