摘要
为了减小单平台和编队平台之间主动声纳对其他声纳的干扰,提出了基于声兼容性分析的声纳频率间隔优化方法。该方法从声兼容性分析的角度出发,首先将受扰声纳放大器输出干扰幅度和检测与跟踪波束域干噪比作为衡量声纳受扰程度的两类关键指标,建立了其计算模型,并通过水池实验验证了模型核心部分的准确性;然后,分析了这两类指标与声纳之间工作频率间隔的关系,提出了基于这两类指标的声纳频率间隔优化方法。
In order to reduce the jammer amplitude of two sonars in the same team,the frequency interval determination method between two active sonars based on underwater acoustic compatibility analysis is proposed.From the view of the underwater acoustic compatibility analysis,two jammer amplitudes and two jam-noise-ratios(JNR)in beams are taken as two types of key indicators,and the calculation models are founded.A cistern experiment demonstrates the accuracy of the model core,and the relations of these four quantities and the frequency interval between two active sonars are analyzed.The frequency interval optimization method between two active sonars based on two types of indicators is proposed,and helps to solve the underwater acoustic compatibility problem among several sonars.
