摘要
板块元法是一种水下目标回声特性的近似计算方法,提高其积分计算的稳定性和快速性是应用中常遇到的问题。将Gordon积分算法引入到板块元方法中,并结合面元声散射特点,对其加以简化。仿真结果表明,所提方法在计算目标回声中不仅有效克服了常规算法中的不稳定问题,也使计算速度得以提高。
Planar element method is one of approximate computation means for echo characteristics of submerged targets. How to improve the stability and rapidity of integral computation is a puzzle. Gordon integral algorithm was introduced into planar element method and simplified in terms of scattering characteristics of facet. The simulation results show that the proposed method not only overcomes the instability problem, but also advances the computation rapidity.
