Abstract
本发明涉及一种海面舰船动态耦合雷达回波信号的生成方法及装置。方法包括：基于预设的雷达运动轨迹和预设的海面舰船运动轨迹，构建雷达照射海面舰船的动态场景；基于动态场景，计算在不同时刻下雷达与海面舰船之间的相对位置，相对位置包括雷达所在位置相对于舰船本体坐标系的俯仰角、方位角以及雷达到舰船几何中心的距离；将电磁波在舰船和海面之间的动态耦合散射路径等效为电磁波在舰船坐标系下的单、双站散射路径；基于雷达与海面舰船之间的相对位置和单、双站散射路径，计算雷达照射海面舰船的综合散射电场；基于综合散射电场，生成雷达照射海面舰船的雷达回波信号。本发明，可以显著提高海面舰船雷达回波的计算效率，工程实用性强。
