摘要
声光相关技术在检测宽带微弱信号中有很大的潜力，提出在射频上用声光相关器对扩频信号做相关运算的方案，给出扩频信号的快速捕获、精密跟踪和信息解调的方法，并设计了实验系统，结果得到了验证．
The acousto-optic correlative technique has many applications in wide band and weaksignal detection. By using acousto-optic correlators, a method of spread spectrum signal cor relative processing is discussed. The mothod of spread spectrum signal fast capture, fine trackand demodulation is proposed. A experimental system is designed and the conclusion has beenproved.
