1·The results indicate that spread spectrum angle tracking system may obtain the same precision as mono pulse beacon tracking system;

结果表明：扩频角跟踪精度可达到单脉冲信标跟踪的精度；

2·For example, tags might be set to beacon every second for tracking the movements of people in a secure area, or every 30 minutes for tracking relatively stable objects like IT assets.

例如，标记可以设置为每秒“发光”一次，以跟踪一个安全区域内的人员的移动；或者设置为每30分钟“发光”一次，以跟踪相对稳定的物体，比如IT资产。

3·In mobile atmosphere laser communication, we often complete acquisition, tracking, pointing and communication by signal laser and beacon laser.

在移动大气激光通信中，通常采用信号光和信标光来完成信号的捕获、跟踪、定位以及通信。
