摘要
针对当前运用多波束系统进行水下失联目标搜索时所布测线效能较低的问题,提出一种改进的测线布设方式.首先,分析并建立了典型测线布设方式的水下目标搜索耗时计算方法,然后对给定条件下搜索耗时的影响因素进行数值模拟计算,从而确定出多波束系统的不同波束开角、船舶长度、区域海水深度等不同因素影响下的测线布设最优方案.试验结果表明,小船作业时,采用梭织法与跨行法的搜索效率明显优于向心法与套行法,大船作业时,采用跨行法的搜索效率最优.这些结论有助于深入了解各因素之间的相互作用和影响规律,进而找出影响搜索效率的主要因素,并提出相应的改进措施和优化建议.
Abstract
In response to the issue of low efficiency in underwater target search using multi-beam systems,this paper proposes an improved method for line deployment.Firstly,it analyzes and establishes a time-consuming calculation method for underwater target search based on typical line deployment methods.Then,numerical simulations are conducted to assess the influencing factors of search time under given conditions,thereby determining the optimal line deployment scheme for multi-beam systems considering factors such as different beam opening angles,vessel lengths,and regional water depths.Experimental results indicate that,during small vessel operations,the efficiency of the search using the weave and cross-line methods is significantly superior to the spiral and loop methods,while during large vessel operations,the cross-line method yields the highest efficiency.These conclusions contribute to a deeper understanding of the interaction and impact patterns among various factors,thereby identifying the primary factors affecting search efficiency and proposing corresponding improvement measures and optimization suggestions.
