| 摘 要： | 由于海面自身的条件及随机多变的特性，目标雷达散射回波会受到不同程度的影响。分别研究了不同海情、蒸发波导以及两种情况共同制约的状态下，舰船目标雷达散射回波情况，并进行了理论分析和岸-舰情况仿真。结果表明：①随海情等级的增加，目标 RCS 减小；②随着波导高度的增加，目标 RCS 增大，且大气湿度对蒸发波导传播有一定影响；③海面的粗糙度会影响蒸发波导传播，随粗糙度的增大，目标 RCS 会变小。研究结果为海面雷达侦测提供了参考依据。

| Abstract: | The RCS of the target is affected by varying degrees for the characteristic and randomness of the sea surface.The paper studies on the RCS of the ship in different sea condition,evaporation duct condition and the mutual conditions mentioned above.The theoretical analysis and the shore -ship simulation are conducted as well.The results show that the target RCS reduces with the increase of sea level;the RCS increases with the increases of evaporation duct height,and the evaporation duct propagation is influenced by air humidity;the evaporation duct propagation is effected by the sea roughness,the target RCS decreases with the increases of sea roughness.The research provides reference for the radar detection. |
