| Abstract: | The development of computer technology prompts wide application of simulation of radar sys- tem. The simulation of environment clutter plays an important role in the simulation of radar. This paper intro- duces Doppler spectrum performance of PD radar ground clutter. The principle of grid superposition for compu- tation of clutter is discussed. A model of scattering factor of clutter is presented, and the amplitude fluctuation and spectrum characteristics of clutter are analyzed. The superposifion method of clutter cell signal is provided. Eventually, a simulation model of video ground clutter is set up, and the 3D power spectrum is plotted. |
