基于ARM控制的紫外光通信系统收发端捕获、对准与跟踪(APT)的研究与实现

Research and Implementation of Acquisition,Alignment and Tracking(APT)of Receiver and Transmit Based on ARM Control UV Communication System

紫外光通信相较于如红外光通信等常规的光通信,具有可非直视通信的优点。与现有的电磁波通信相比,紫外光通信又具有保密性较高、抗干扰能力较强的优点。基于紫外光通信的优点,有高校已经设计出将通信过程分为直视通信与非直视通信,且在通信过程中可以很好地衔接双向通信机的硬件,根据前人提出的捕获、对准与跟踪(APT)方法的理论知识,通过STM32微处理器进行实现。实验证明,通过波形采集法实现的APT可以达到通信要求。

Compared with conventional optical communication such as infrared optical communication,ultraviolet optical communication has the advantages of non-direct communication;And compared with the existing electromagnetic wave communication,it has the advantages of higher confidentiality and stronger anti-interference ability.Based on its advantages,some major universities have designed two-way communicators that can divide the communication process into direct-view and non-direct-view communication.According to the theoretical knowledge of the capture,alignment and tracking(APT)method proposed by the predecessors,through STM32 implements and conducts experiments.The experiments prove that the APT realized by the waveform acquisition method can meet the communication requirements.
