Research And Design Of Radar Simulator

Simulator is a good equipment, which can be used for training operation and repairing of relative equipment. This method is an inevitable trend of development. The radar simulator researched in this paper is an equipment which can simulate different types of navigation radar' function and user interface. The simulator can generate realistic island and moving target echoes in relative area, in addition, it can also determine target's azimuth and distance. Modularization and flexible collocate method can make the processing of simulation for software function and real target change easily between different requirements. So it can be used in not only real operation training, but also research in different fields, such as radar system frame, radar signal process, and radar clutter.After referring to extensive literature, the paper accomplish the simulation of sea clutter, including Rayleigh distribution, Log-Normal distribution, Weibull distribution, and K-distribution. In the part of target simulation, the simulation method is focused on the aspects of distance, azimuth and dithering. As to the ground echoes, the important problem is shelter. Through researching the character of microwave transmission, we give a new gene named shelter gene as a discuss focus.In addition, we have designed a feasible framework for the radar simulator based on the real navigation radar in the paper. The paper gives out the design principle and method of database, labour design method of the information flat roof and logical relation. And we designs the parameter input dialog, and analyze the relationship between the parameters and radar system. As to the UI, we focus on the two parts: how to operate and how to achieve, and analyze the method of software and theory. According to teaching and training function, system is designed into two parts, teaching PC and student PC. In the implementation of the project, we make full use of all the features of computer language, and also make their respective advantages play well. In the internal image signal process algorithms, C language is used in design. Call and external network was mainly completed by C + +. Database's design and management refer to the high-level language C# and ADO.net. The entire system, with the support of various languages, achieved the proper effect.
