摘要: 研究了一种用于我国近海海域隐蔽式军事侦察的小型漂浮式卫星天线横滚角的动态处理方法。从理论上研究横滚角对天线与卫星通信的影响,以及横滚角变化与方位角和极化角变化的关系;研究通过方位角和极化角的补偿来隔离横滚角变化对通信影响的横滚角动态处理方法;以4级海况下漂浮式天线系统的横滚角度变化情况为测试样例,比较横滚角动态补偿方法和4轴伺服补偿过程中自动增益控制(AGC)的变化情况,证实了横滚角动态处理方法切实可行。

Abstract: A dynamic processing method of roll angle of small floating maritime satellite antenna, which is applied in military concealed reconnaissance, is studied. The influence of roll angle on the quality of communication, the relation between azimuth and roll angles as well as the relation between elevation and roll angles are studied in theory. A dynamic processing method of that the compensations of the azimuth and elevation angles are applied to isolate the influence of the roll angle on communication is proposed. The relational expression among AGC, azimuth and elevation is fitted by the least square method based on the sampling data. The proposed method for roll angel of the small floating antenna is feasible by comparing the changes of AGC in the process of dynamic processing to the changes of AGC in the process of 4-axis servo compensation.
