SATSOFT/PO  Physical Optics Reflector Modeling Option

Expand the capabilities of SATSOFT with SATSOFT/PO. Provides the same ease of use as SATSOFT/AR, the Analytic Reflector Model, but with greater accuracy and expanded capabilities. Physical Optics is the industry standard method for performing reflector analysis, and provides the most accurate predictions of directivity, scan aberration and crosspol available. SATSOFT/PO is a vector reflector modeling program that integrates the reflector's surface currents to produce accurate far-field predictions for both copol and crosspol. Quickly perform reflector trade-studies with the most accurate analysis available.

Features

• Vector model computes both copol and crosspol patterns

• Whittaker/Shannon reconstruction reduces the number of computed points, speeding computation and reducing pattern storage by an order of magnitude.

• Linear or circular polarization

• Accurate beam scan-aberration

• Multi-beam and shaped beam designs

• Single and dual mode (Potter) circular feed models

• Uses well-established physical optics method

• Circular or elliptical apertures, arbitrary orientation

• Solid or gridded reflector surfaces to allow for crosspol reduction and shared apertures

• Easy to use and fully integrated with SATSOFT Satellite Coverage Design Software

• Reflector geometry dialog automates selection of parameters

• Fast field computations using Gaussian integration method

• Works seamlessly with SATSOFT’s built in shaped beam optimizer

• Feed positions computed automatically from secondary beam centers

• Plot patterns of directivity, EIRP, crosspol, crosspol C/I, G/T, and other parameters

• Component beams are stored and reused to speed up subsequent composite beam optimizations.

• Export reflector geometry in GRASP7 format
