Research On The Modeling And Simulation Method Of Typical Targets And Environment

With the technology development and worsening working conditions, Radar system has become increasingly large, complex, and high speed, while the radar systems development cycle is long and expensive, so the radar system simulation technology has become a hot research in the current. And the radar echo simulation is the most critical part of the radar system simulation. When the radar echo during simulation, we are facing a situation which is target diverse and environment complexly. So developed a typical targets and environment library which is reusable, scalable and easy to integrate into the radar system simulation has become a hot spot in the radar system simulation research. This paper is based on this idea and carried out research work.Firstly, this paper research the modeling and simulation the radar echo data which is include the target echo data, war-field electromagnetic environment data and clutter echo data. And modeling and simulation some typical targets and environment models. Then building a library use C++ code to the typical target and environment models, and gives the detailed design process and class diagram. The main contents are as follows:1、Researching the fluctuation statistical model of radar cross section and target scattering properties. Giving some typical targets model and its RCS data. Modeling and analysis of narrow-band and wide-band echo method.2、Researching and modeling of Radar transmit signal, Communication signal, active blanket jamming, active deceive jamming and chaff cloud jamming. Discussed the tropospheric refraction and absorption model.3、Introducing the basic ideal of modeling and simulation method of clutter statistical model. Modeling and simulation of ground radar land clutter, sea clutter and weather clutter. And Gives some land, sea and weather clutter coefficient models.4、introducing the basic knowledge of radar echo data amalgamation. Making a detailed research on typical targets and environment library, and gives the detailed design process and class diagram.
