Easy setup of reflector antennas fed by a single or multiple feeds

By specifying a minimum of parameters such as the antenna diameter or desired beamwidth, SATSOFT will set up a reflector system based on simple design rules to generate a blockage-free array-fed system. Far-field predictions of directivity and crosspol from linearly or circularly polarized reflector antennas fed by fundamental-mode or dual-mode feeds are computed using a fast and accurate PO implementation.

Design of HTS payload

Scan aberration and spillover loss are accounted for in the analysis to provide accurate performance data for the scanned beams in multiple-spotbeam reflector systems with 3- or 4-color frequency reuse, or in the beams generated by a digital beamformer.

Accurate modeling of frequency dependence

The physical optics module allows you to easily investigate the influence on the antenna performance of changing frequencies. This is a useful feature, e.g., for estimating the impact of different receive and transmit bands.
