英文摘要：

A new hybrid DS/FH signal generator based on spatiotemporal chaos was proposed, in which not only the system security is strengthened by spatiotemporal chaos but also the real time PN codes and FH patterns are generated synchronously through a single mechanism. In this mechanism it is easier to control and change parameters for better security, and the period of PN spread-spectrum sequences and FH patterns are also easier to control and can be arbitrarily long. And some analyses about the properties of spatiotemporal chaotic hybrid DS/FH signal generated were also given. The simulation results show that not only the PN spread-spectrum sequences but also the frequency hopping patterns have ideal balance and correlation properties.
