中文摘要:
      为了解决传统拖线阵存在的左右舷模糊问题,已经发展了双线阵和三元组集束的线列阵.这两种结构的线列阵在通常情况下都可以较好地完成使命,但在实际应用中还可能会遇到一些困难.对同时存在多个目标且舷角值比较接近时影响其左右舷分辨结果的几种情况做了分析,提出了利用多目标运动的方位连续性修正其左、右舷分辨结果的新技术,提高了上述两种结构线列阵左右舷分辨结果的准确性和抗干扰能力.仿真结果验证了新方法的有效性,并对三元组线列阵海上实验数据进行处理,结果验证了新方法的稳健性,可望应用于工程实践中.
英文摘要:
      The twin-line array and line array with hydrophone triplets have been applied to removing the port/starboard ambiguity.Each of them can work well in most conditions,but not always so in conditions of targets'bearings close each other.Several typical cases are analyzed and a new bearing continuity method is proposed to improve the performance of port/starboard discrimination in this paper.The validity is verified by simulation results,and the sea-trial data acquired from line array with hydrophone triplets is analyzed to show the robustness of the method.It's expected that this method can be used for towed line array sonar.
