中文摘要:
      采用常规单线拖曳阵列作为双基地主动声呐的接收平台时,会存在左右舷模糊。常规左右舷判决方法需要声呐探测平台进行转弯等复杂机动,目标定位与跟踪的实时性和连续性难以保证。文章对利用回波多普勒效应实时判断低速目标左右舷的方法进行了研究,给出了目标低速运动的条件,并分析了多普勒响应可分辨特性与声呐平台位置、运动状态的关系。通过仿真实验验证了该方法的可行性与有效性。海试数据处理结果表明,声源船仅具漂流速度时即可通过回波多普勒信息有效判别静止浮台目标的左右舷。该方法可以作为双基地主动声呐探测与定位系统中的辅助手段。
英文摘要:
      The problem of target port/starboard ambiguity exists when the towed linear array is used as the bistatic active sonar receiving platform. The traditional method to solve this problem is to require the towing ship performing complex maneuvers, however, the real-time and continuous target tracking is difficult to guarantee. In this paper, the method using Doppler information to judge the of low speed targets on the port/starboard sides of a single linear array is studied. Conditions for the low-speed motion of the target are listed, and the relationships of Doppler information with sonar platform position and movement state are analyzed. Simulation and sea trial results show that the port/ starboard information of the target can be effectively discriminated by this method, which can be used as an auxiliary means in the bistatic active sonar.
