摘要
Abstract
Electronic warfare system usually uses a wide instantaneous bandwidth, in which may exist DSSS signals, in non-cooperative context such as spectrum surveillance, whether there exists DSSS signal, the number of signals and their position in frequency domain are all unknown. A new multi DSSS signals detection method aimed at this situation is presented. This method uses fluctuations of correlation estimators, with the help of band-pass filters, makes every DSSS signal isolate in frequency domain, and enhances signal to noise ratio. Then, an analysis of performance of this method is presented. The computer simulation demonstrates the effectiveness and the practicality of this method.关键词
