摘要: 提出用时间积分声光相关器进行长码的捕捉.以相加时间积分声光相关器为实验系统模型,把系统划分成光源部分、分束部分、扩束部分和光电检测部分,通过对各部分的分析和计算,建立了实验的最佳方案,并用该模型进行了时间积分声光相关器的实验,对实验结果进行了分析.首次在国内完成了时间积分声光实验模型,并给出了满意的实验结果.Abstract: The time-integrating acoustic-optical correlator was used to capture long codes. The additive time-integrating acoustic-optical correlator was used as the experimental model. The experimental model was devided into four parts: light source, splitter, beam expansion and detector array parts . Through the analysis and calculation for each part, the optimum experimental model was established. The experiment of time-integrating acoustic-optical correlator was finished by use this experimental model, and the result was analyzed. It is the first time the experimental model of time-integrating acoustic-optical correlator was finished in our country and at the end of this paper, the satisfied experimental results in our laboratory were given.
