| Abstract: | 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. |
