Signal Propagation and Environment

Channel propagation, radar cross section, Swerling targets, clutter, jammers

The Phased Array System Toolbox™ lets you model free-space signal propagation from source to target and return. Free space propagation models include range-dependent time delay, phase shift, Doppler shift, and attenuation. You can specify scattering radar cross sections (RCS) for point-target reflectors for nonpolarized and polarized radiation. The toolbox lets you create collections of distributed point reflectors for complex, distributed targets. The four standard Swerling target models are implemented. In addition, clutter and jammer models are provided.
