摘要
分析大型舰船类目标高频电磁散射特性对未来海战具有重要实用意义。针对当前目标高频电磁散射计算精度有限的问题,在CAD构建舰船表面模型的基础上,用多层快速多极子方法(MLFMA)对舰船类目标进行高频电磁散射截面进行分析。仿真结果表明,多层快速多级子算法能准确快速预估大型舰船目标的高频散射截面,并且具有耗时较少的特点,为高频雷达系统的研究及舰船设计提供有效的参考数据。
It＇s of practical importance to analyze scattering characteristic of large ship targets with respect to high frequency（HF）radar in future maritime warfare.Aiming at the limited accuracy problem of general HF methods,and based on modeling the ship surface model by CAD,HF radar cross section（RCS）of ship targets was calculated by multilevel fast multi-pole algorithm（MLFMA）.Simulated results indicate that HF RCS of large ship targets can be calculated fast and accurately by MLFMA and is less time-consuming,which can provide effective data reference for HF radar system research and ship design.
