| 摘 要： | 由海底散射引起的混响是影响双基地声纳性能的重要因素之一,为了通过合理配置双基地声纳各角度来减小海底散射对双基地声纳的影响,基于小斜度近似(SSA)理论,建立了双基地海底散射强度模型.给出了散射强度与双基地声纳各角度之间的关系式.仿真结果表明.海底散射强度与双基地声纳各角度配置关系复杂,随着各角度配置的不同,散射强度会有很大的变化,但在镜反射方向上取得最大值.小斜度近似在整个入射角范围内较为准确,是一种处理粗糙面声散射问题的好方法.

| Abstract: | The reverberation caused by ocean bottom scattering is an important factor to influence the performance of the bistatic sonar.For reducing the influence,relationships between the bistatic scattering strength and angles configuration are studied,and a bistatic scattering model is presented based on Small Slope Approximation(SSA) theory.Simulation results show that relationships between the bottom scattering and the angles are complex.It is found out that scattering strength varies with different angles and r... |
