摘要
本文研究用声光器件实现实时相关的处理方法，推导了声光信号处理器的数学模型，提出了一种能对长码扩频信号进行相关处理的宽带时间积分型声光信号处理系统，并对其设计和性能进行了分析实验结果表明。
In this paper, the methods of real-time correlation operation performed by the acoustooptic Bragg cell are discussed. The mathematical models of the time-integrating acoustcroptic signal processing system that provides the correlation for spread spectrum singals with a long Cede are developed,and the design and performance of this system are described. 14. using this architecture, a desired pceossing gain of 57 dB can be achieved with a large bandwidth of 62MHz.
