[Abstract]:The study of battlefield electromagnetic environment has been paid much attention by many countries. It is precisely because more and more electronic warfare is used in the battlefield all over the world. Interference, confusion, inducement, deception, and various sources of radiation disturb the "eyes" of both sides of the war on the battlefield, distinguishing and discovering that real targets are the key to dominating the battlefield. In this paper, the emitter model and the passive interference model are first constructed, and the efficient instantaneous autocorrelation algorithm is used for signal sorting and recognition, and the simulation software is written according to the needs of practical applications. The main work and contributions of this paper are as follows: (1) the important position of battlefield electromagnetic environment simulation in the present battlefield is briefly introduced, and the current research status of electromagnetic environment simulation at home and abroad is analyzed. The significance of the research is also expounded. (2) the emitter signal is constructed, including all kinds of emitter signal and echo signal. The modeling objects include uniform pulse train signal, linear frequency modulation signal, agile frequency conversion signal, target echo signal, clutter and receiver noise. (3) the drawing frame of MFC control window combined with OpenGL is established to draw emitter and radiation range; The MapX two-dimensional map is introduced and redeveloped to realize the display of electromagnetic environment in China and offshore areas. With reference to the development documents provided by MapX, the functions on the map are further improved and optimized by its API. It lays the foundation for the whole system to provide good human-computer interaction, and completes the visualization display of electromagnetic environment simulation. (4) in the design of the system, the intermediary mode, the observer pattern and the singleton pattern are used to design the system. The program is easy to maintain, easy to expand, easy to reuse and flexible. It reduces the coupling between modules in object-oriented programming, and optimizes the code to some extent. (5) Design equipment carrier database, utilize the ADO interface provided by Microsoft, The connection relational database SQL Server 2008 R2 is implemented in VS 2010, and the SQL statement is read in the form of reading string in VS. The operation of adding and deleting the equipment carrier database under the MFC framework is completed.
