摘　　要：目前,步进跟踪已成为卫星通信地球站的主要跟踪手段。传统步进跟踪方法的主要逻辑为控制天线向信号最强处靠拢,在小范围内搜索,然后向信号强度大的方向运动,循环往复,达到跟踪的目的。“收拢”式跟踪突破向信号强度最大位置靠拢的概念,直接将中心包在一定范围内,然后根据信号值不断调整方位,实现精确跟踪。工程实践证明,“收拢”式跟踪取得良好的跟踪效果,能适应多种环境,跟踪精度高,是一种高效稳定的步进跟踪方法。At present,step tracking has become the main tracking method for satellite communication earth stations.The main logic of traditional step tracking methods is to control the antenna to approach the strongest signal,search in a small range,and then move in the direction of high signal strength,in a cyclic manner,to achieve the purpose of tracking.The"collapse"tracking breaks through the concept of approaching the position with the highest signal strength,directly wrapping the center within a certain range,and then continuously adjusting the orientation based on the signal value to achieve precise tracking.Engineering practice has proven that the"folding"tracking method achieves good tracking results,can adapt to various environments,has high tracking accuracy,and is an efficient and stable step tracking method.
