摘要
提出一种恒线速度螺旋扫描捕获算法,推导出了天线X轴、Y轴转动角计算公式,保证了在天线指向存在误差情况下,用户星中继终端天线仍能准确转入自动跟踪.叙述了扫描参数选择,算法可以实现目标角度全覆盖扫描,天线转速稳定,对卫星姿态影响较小,有利于用户星天线迅速捕获跟踪中继星.
An acquisition algorithm of spiral-scanning is proposed. The formula of rotating-angle calculating of XY-axis is deduced. The method assures that relay terminals of user satellites have the abilities of switching into auto-tracking mode exactly under the circumstance of error pointing. Full coverage of Target angle scanning,stable rotating speed,little effect on satellite attitude and advantage in fast acquisition of TDRS by user satellite＇s antenna can be achieved by choosing scanning parameters.
