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. 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
|Billingsley’s intrinsic clutter motion (ICM) model|
|Depression angle of surface target|
|Grazing angle of surface target|
|Gamma value for different terrains|
|Surface clutter radar cross section (RCS)|
Propagation environments have significant effects on the amplitude, phase, and shape of propagating space-time wavefields.
What are polarized fields?
This section introduces the concept of baseband signals and defines the local and global coordinate systems used in the toolbox.
