摘要

摘要: 不同风浪等级下的海面会对船舰目标雷达散射截面(RCS)分析产生强烈影响。该文建立了一种船舰模型，利用物理光学法与矩量法的混合算法(PO-MOM)分析了不同海情下的船舰目标远场单站RCS。之后研究了海情对船舰目标RCS测试结果的影响。最后提出了基于3次样条插值(Cubic Spline Interpolation, CSI)算法的优化补偿方法。结果表明，随着海情等级的增加，舰船RCS降低；利用3次样条插值算法进行补偿，其补偿结果的平均值误差小于0.38 dBsm，最大值误差小于0.05 dBsm，因此能有效地减少海情对船舰RCS测试结果的影响。

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.
