摘要
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。畅通的通信链路以及稳定的接收信号对通信的建立是至关重要的。如何计算信号、信标光的接收视场角的大小 ,是决定链路能否畅通 ,接收信号能否稳定的重要因素。对移动大气激光通信中接收视场角的设计进行了研究和分析 ,并根据大气激光通信传输方程和黑体辐射理论提出了一种计算移动大气激光通信中信号信标光发射接收视场大小的方法 。
In mobile atmosphere laser communication, we often complete acquisition, tracking, pointing and communication by signal laser and beacon laser. Expedite communication link and steady received signal is very important to communication's building. Caculating the signal and beacon receive field of view angle is important to expedite communication and steady received signal. In this paper, based on atmosphere communication propagating equation and the theory of blackbody radiation, a method is designed to caculate the signal and beacon receive field of view angle.It is a quantitative analysis method for realization of mobile atmosphere laser communication.
