A radar or sonar system simulation requires models for wave propagation, clutter and interference, array and target motion, and target cross-section. The Phased Array System Toolbox™ lets you model free-space signal propagation in monostatic or bistatic scenarios. Alternatively, you can employ simple multipath propagation using a two-ray propagation model. You can model atmospheric attenuation using line-of-sight (LOS) propagation models. These models calculate signal propagation through atmospheric gases, rain, and fog and clouds. All models include range-dependent time delay, phase shift, Doppler shift, and free-space loss. You can also model the target scattering, specifying scattering radar cross sections (RCS) for point-target reflectors for nonpolarized and polarized radiation. The toolbox implements the four standard Swerling target radar cross-section models. In addition, clutter and jammer models are provided. The toolbox supports constant velocity and constant acceleration motion models.
The toolbox supports sonar system simulation by providing multipath propagation models, hydrophone and projector models, underwater noise sources and target strength models. Target strength models let you create nonfluctuating and Swerling fluctuating targets.
