| 摘 要： | 利用GPS反射信号遥感陆地和海面的GPS—R技术已经得到日益关注。对海面反射信号的极化特性进行分析，分析结果表明：GPS信号经海面反射后，反射信号同时包含右旋和左旋信号，且两者强度与卫星仰角有直接关系；反射的左旋和右旋信号的功率相差可高达30dB。为海面遥感以及专门的GPS接收机的研制提供了必要的参数支撑。 |

| Abstract: | GPS-R,the technique of remote sensing land and sea surface using the GPS reflected signal,has been increasingly paid attention to.The simulation results indicates that both right-and left-hand circular polarized GPS signals are generated after reflection from sea surface,and their strength is different and has a close relationship with the satellite elevations.The power difference between right-and left-hand signals is higher to 30dB.And these are the necessary parameters for remote sensing sea surface and ... |
