Research On Weak Signal Of SH-COS Chaotic Detection And Remote Transmission And Storage System

With the rapid development of length distance communication technology of microwave communication,satellite communication,the application of ship shore communication,data collection and integrated navigation technology are constantly rich,the information transmission develops from wired to wireless gradually.The current detection and data transmission and storage of acoustic wave weak signals of land air and ocean environment is a hot research topic,which is conducive to intelligent acoustic weak signal detection in the future,and is of great significance to the further development of research method of the acoustic wave weak signal detection.In this paper,Weak signal of SH-COS chaotic detection and remote transmission and storage system including chaotic weak signal detection,Beidou short message communication,database website three part,the main function of the system is based on chaotic weak signal detection system to detect underwater acoustic signal,and then use the BD antenna for data transmission,and finally make the data stored in the database for subsequent research.The part of Chaotic weak signal detection analyzes the characteristics of the traditional Duffing system,and finds that it is difficult to distinguish between chaos and large cycle state and the unstable state of large period.To improve these shortcomings,This paper designs a new SH-COS chaotic weak signal detection system,makes dynamic analysis and Simulation of the Multisim and Matlab based on chaotic theory,and makes comparison with Duffing system,which has proved that the new system has the characteristics of anti noise performance,wide signal detection and accuracy in detection and improves the detection of weak signal characteristics of chaotic systems further.The new SH-COS system is used to design a new chaotic communication system,which provides the necessary bridge for the effective transmission of underwater acoustic signals.When the acoustic wave weak signal is detected,the safe and effective transmission is the next concern.Considering the limitation of the complex environment of certain landocean to the communication technology,the Beidou satellite is chosen as the main communication tool.It has the advantages of large coverage area,no communication blind area,and it is suitable for a wide range of data collection,data transmission and other applications.In this paper,the principle of the Beidou short message communication is analyzed,and the communication protocol is interpreted,and the effective transmission of the data is realized through the actual Beidou short message test.Finally,the dynamic website of the system is designed to manage all the data effectively.According to the actual needs,the use of JSP programming language,SQL Server 2005 database complete the fouction design of database website system,which includes user registration and login,information input and output,user management,and achieve the effective management and query of test data.
