The toolbox models target reflection and scattering by point-like reflectors. You can specify scattering radar cross sections (RCS) for non-polarized radiation or scattering matrices for polarized radiation. The four standard Swerling target scattering models are implemented. For the special case of backscattering radar scenarios, you can simulate an angle-dependent radar cross-section model. Radar cross-section models apply to both narrowband and wideband signals. Clutter and jammer models let you model land and sea reflections and interference sources. You can also simulate the four standard Swerling backscattering models in sonar scenarios. The toolbox enables you to simulate radar reflections from a walking pedestrian or a moving bicyclist. For sonar system simulations, you can employ target strength models and create underwater noise sources. To simulate clutter, you can use a computer graphical processing unit (GPU) to speed up computations. In this case, use the phased.gpu.ConstantGammaClutter System object™.
