摘要

摘要: 研究潜艇目标回声的近、远场过渡特性对于主动声纳探潜、探测和水声对抗具有实际意义。计算目标回声强度随距离变化曲线是分析目标回声近、远场过渡特性的一种有效方法。理论分析和试验研究均表明, 在鱼雷自导频率下, 目标回波可近似看成是目标亮点回波相干叠加的结果。该文提出了一种基于亮点模型的潜艇目标回声过渡特性分析方法, 通过亮点模型计算不同距离情况下的潜艇目标的回声强度值, 进而分析潜艇目标回声的近、远场过渡特性, 并与板块元算法计算回声强度值分析潜艇目标过渡特性进行了对比。仿真结果表明, 该方法简单, 高效。

Abstract: Transition characteristics of echoes from submarine are essential in studying submarine detection and acoustic countermeasure. Calculating echo strength from an underwater target versus distance is an effective method for analyz-ing transition characteristics of echoes from underwater targets. Theoretical analyses and experiments have shown that under high frequency, echo from any complex target can be considered a coherent superposition of waves from high-lights. A novel algorithm is presented in this paper based on a highlight model to calculate the submarine echo strength in different distance, and to analyze the transition characteristics of echoes from a submarine. Simulation results show that the proposed method is simpler and more efficient compared with the planar element method.
