RADAR Antenna Models in VSS

RX antenna model can have multiple inputs to allow for interfering signals and/or

clutter

– THETA and PHI can be specified for Desired Signal, Jammer, Clutter,

etc….

– Corresponding gain and phase are picked off antenna pattern

Desired signal

& Clutter

Jammer

Multiple Theta Phi cuts
