| With the innovation and development of radar technology,the learning threshold of radar basic theory is higher and higher,and the learning difficulty is gradually increased.In order to reduce the learning difficulty of radar related majors,a simulation experiment software of Radar Virtual experiment is developed,providing auxiliary teaching for radar basic theory.The software covered the knowledge of the radar principle and radar system,it is based on the idea of virtual experiment,combining radar computer simulation with network virtual laboratory,using a variety of rich experimental content,combined with flexible and vivid way of display,weakening theoretical deduction,let students through a variety of virtual experiments to deepen the understanding of radar basic theory and radar system simulation.At the same time,the software supports remote learning and makes rational use of teaching resources.The modular design concept provides convenience for adding new content at the large stage.It is of great practical significance to develop Radar Virtual Experiment Simulation Software.Firstly,this thesis selects the software development platform.At the same time,the operation process of traditional experiment is used for reference,the general framework of Radar Virtual experiment simulation software is determined.The software framework is developed by means of hybrid programming based on Visual C++ and MATLAB;Secondly,in order to realize the network function of virtual experiment,C/S architecture is used to develop the terminal and server of virtual experiment.The Access software is used to manage the students' data of the sever,the operation flow of the software is designed,and the experimental contents are determined.The eight broad categories of basic radar theory,radar antennas,radar transmitter,radar receiver,radar signal processing,radar data processing,new systems and technologies radar,radar system are classified.The specific experiment contents are designed for these eight classes,and the experiment of each module is designed concretely;Then,from three aspects of software interface,software terminal and software sever,the system development of software is introduced in detail,among them,the software interface mainly includes three parts: system login interface,experimental software main interface and sever management interface,the software terminal mainly involves the development environment configuration,the algorithm kernel design,the interface function call and so on the key technologies,the software sever mainly includes database configuration,network programming and other key technologies.Through the collaborative development of three parts,the simulation software of Radar Virtual experiment is developed;Finally,the virtual experiment simulation software of radar is tested systematically,through standardized testing and code standardization and unified management,the software is tested from three parts of the algorithm kernel,the interface and the sever.The completeness of the software function and the correctness of the results are verified. |
