Design And Implementation Of The Integrated Management And Control System Of Signal Simulator

With the rapid development of radar and communication technology,the use of signal simulators to simulate real signals to build a complex electromagnetic environment has become an important means of radar system development and testing,and is widely used in modern electronic countermeasures,electronic reconnaissance and radar communications.The thesis comes from a signal simulation system project.The whole system is divided into a radar signal simulator,a communication signal simulator,and an integrated management and control system.The integrated management and control system is the core of the signal simulator system.The optical fiber communication link provided by the road and the optical fiber module performs centralized and unified control of the radar signal simulator and the communication signal simulator to realize the analog output of the radar signal and the communication signal.The integrated management and control system is based on the Qt control software development method.It is developed in the Qt Creator environment using the C++ programming language.Through a friendly graphical user interface,the test scene description,parameter test process management and test work status monitoring are completed,and the MySQL database can be used.Manage radar data and communication data to achieve parameter recording and other work.The main work of the paper is as follows:1.According to the requirements of the signal simulation system,the system functions and composition are given,the hardware platform of the signal simulation system is built,the requirements of the integrated management and control system are analyzed,and the overall design of the signal simulation system is completed.2.Based on Qt's control software development technology,the application of QWidget class,signal and slot mechanism and multi-threading technology in Qt in this system is studied,and the connection and operation of MySQL database based on Qt platform are studied,and the network communication is deeply understood Technology to provide technical support for the specific implementation of the functions of each module of the integrated management and control system.3.Implement each module of the integrated management and control system,focusing on the analysis of the main control module,network communication module,parameter management module and database module,based on Qt and using object-oriented programming technology to achieve its module function In order to improve software efficiency and make the system run more smoothly,software programming uses a multi-thread method.4.Finally,on-line test on the radar signal simulator and communication signal simulator,the test content includes network communication,parameter setting and delivery,database operation,system control and display output.The test results show that the integrated management and control system designed in this paper has complete functions and runs smoothly,meeting the system functional requirements.
