| Abstract: | The model and simulation of low grazing angle sea clutter is introduced. According to the actual background, some approximate models of sea clutter have been modified. Simulation schemes are presented in detail for incoherent and coherent radar signal processing respectively. Some key problems encountered in the simulation are emphasized, and a software of simulation is realized in Visual C++. The results of simulation show the applicability and effectiveness of the model and the simulation scheme. |
