摘要

摘要: 不同風浪等級下的海面會對船艦目標雷達散射截面(RCS)分析產生強烈影響。該文建立了一種船艦模型，利用物理光學法與矩量法的混合算法(PO-MOM)分析了不同海情下的船艦目標遠場單站RCS。之后研究了海情對船艦目標RCS測試結果的影響。最后提出了基于3次樣條插值(Cubic Spline Interpolation, CSI)算法的優(yōu)化補償方法。結果表明，隨著海情等級的增加，艦船RCS降低；利用3次樣條插值算法進行補償，其補償結果的平均值誤差小于0.38 dBsm，最大值誤差小于0.05 dBsm，因此能有效地減少海情對船艦RCS測試結果的影響。

Abstract: The sea under different wave levels has an strong impact on the ship target Radar Cross Section (RCS) analysis. The far-field single-station RCS analysis model is established for the ship under different sea conditions based on the Physical Optics with Method Of Moments (PO-MOM) hybrid algorithm. Then the impact of sea conditions on ship RCS results is studied. The ship RCS results are reduced with the sea wave level increasing. Finally, an optimization ship RCS compensation method is proposed under different sea conditions based on Cubic Spline Interpolation (CSI) algorithm. The results show that the average value error and maximum value error of ship RCS results are less than 0.38 dBsm and 0.05 dBsm, respectively by employing the proposed method, which can reduce the influence of sea conditions on ship RCS analysis effectively.
