以单水听器阵列构成的单线阵声呐无法区分目标来自左舷或右舷。多线阵为解决左右舷目标的模糊问题提供了一种途径,本文讨论双线列阵左右舷目标分辨的性能,提出把波束指向方向的响应对对称方向的响应的抑制比作为评估左右舷分辨能力的一个参数,并对抑制比的性能作了初步分析,给出了理论表达及实际计算结果。理论分析结果对实际双线列阵设计中的参数选择具有重要意义。
Single-line sonar array consisting of single-line sonar can not distinguish between the target from the port or starboard. The multi-line array provides a way to solve the ambiguity problem of the port and starboard targets. In this paper, the performance of the port-to-starboard target discrimination of the dual line array is discussed. The suppression ratio of the response of the beam direction to the symmetrical direction is proposed as Ability of a parameter, and the performance of the suppression ratio made a preliminary analysis, given the theoretical expression and the actual calculation results. The result of theoretical analysis is of great significance to the parameter selection in practical double line array design.
