| The simulation of radar clutter mainly simulates the echoes under a certain environment. Then analyze the features such as amplitude distribution for the debugging of radar system and radar signal process. With the development of radar technology, the system becomes much complex and the experiment outside becomes more difficult. So it is of great significance to study the simulation of radar clutter.This paper mainly studies the clutter of the system of airborne radar. Firstly, types of clutter and the method of clutter simulation are given. Then analyze the characteristics of the amplitude of clutter and simulate clutter sequence obeying different distributions and comparing with the theoretical clutter models. In addition, the applications of clutter models in different environments are given. According to the analysis, the speed of airborne, beam width of antenna and the azimuth of antenna are important factors for the ground clutter of airborne radar. Use the changes of the clutter spectrum to verify the influence of the factors above to clutter. And study how the distance fuzzy and Doppler fuzzy affects the clutter. Finally, study the influence of the speed to the clutter according to the simulation of a unit of ground clutter. Analyze methods of dividing the scattering region such as Distance-Doppler and range ring. Then simulate the side-looking airborne clutter in linear frequency modulation system using the method of rang ring. And analyze the shape of ground clutter ridge in different yaw angles. |
