phased array system toolbox™ lets you create narrowband signal waveforms that are radiated by antennas, microphones, sonar transducers, and arrays. narrowband signals fall into pulsed and continuous types. waveform types include rectangular, frequency-modulated continuous, phase-coded, and stepped-frequency signals. in addition, matched filter algorithms are provided to perform coherent processing. the toolbox lets you create and plot ambiguity functions.

the toolbox also lets you model free-space signal propagation in monostatic or bistatic scenarios with targets and arrays in motion. alternatively, you 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 specify scattering radar cross sections (rcs) for nonpolarized radiation or scattering matrices for polarized radiation. the toolbox implements the four standard swerling target radar cross-section models.
