| Abstract: | To perform the simulation of ground clutter received by space-based pulse doppler(PD) radar,a method based on the analysis of cohered video is illustrated in this paper.Its theory and basic principles are discussed in detail,as well as its computing formula and realization steps.The radar's ground clutter spectrum is analyzed theoretically.Finally,the simulation and analysis of relations between mainlobe clutter and antenna angle of view,and between mainlobe clutter and earth rotation are performed.The agreement of final simulation results with theoretical results indicates that this method can be used to estimate the earth surface clutter of space-based PD radar correctly and effectively. |
