| With the rapid development of information technology, wars for marine resources transform from the traditional war towards the information battle gradually. The navy construction is put in an important position in modern army building in the world. The navy has become an strategic troops to protect our country. With the rising status of Navy, the marine radar has embarked on the stage of history and began to play an increasingly important role.Marine radar is an important equipment of modern navy. It takes an major role on detecting and tracking the sea surface and air targets.The marine radar system modeling in the complex electromagnetic environment is accomplished in this thesis. By combing the radar system and the display and control platform, we can control radar system conveniently and browse the simulation results directly. The system is built on the Visual Studio 2005 development platform in C++ language which simulates the radar detection and tracking the sea surface and air targets and eliminating clutter and jamming in the complex electromagnetic environment.The overall scheme of the radar system is proposed firstly on the basis of a marine radar system requirements. Then we put forward a framework and some mathematical models required in the radar system according to the scheme including the complex electromagnetic environment model, the antenna model, the receiver model, the signal processing model and the data processing model. At the same time we describe the physical meaning and the modeling method of each model.This marine radar system is built based on the standardized and modular idea, which is convenient to modify it subsequently. At the same time, through combining the radar system and the display and control platform, we can control it conveniently and browse the simulation results directly. |
