product description

Description

General source models

In addition to the built-in mathematical models to simulate feed radiation patterns, it is possible to utilize more realistic patterns stemming from measurements or predictions from specialized feed design programs such as CHAMP. Moreover, since any feed data imported from file will automatically be expanded in spherical wave modes, the subsequent computation of e.g. induced PO currents will be based on the actual feed near-field performance rather than the far field. Particularly in dual offset VSATs, the subreflector is placed very close to the feed where the source field may differ substantially from the far field.

Analysis and design of reflector antenna systems

Dedicated software for reflector systems, enabling fast and accurate analysis and design of the most advanced reflector antenna systems. Multiple antennas may be defined within the same project, and the general command structure enables the user to define which of those will be considered during a given analysis. This opens for the possibility of making advanced scattering analysis of clusters of antennas. GRASP offers an advanced PO algorithm as the baseline analysis method, supplemented by optional GTD and Moment Method solvers for advanced applications.

 

 
 

Easy definition of single and dual reflector geometries by built-in wizard

The intuitive wizard in GRASP allows for easy setup of single reflectors, Gregorian and Cassegrain systems as well as axially displaced dual reflectors. The wizard generates a good starting point for continued and more elaborate investigation of antenna designs. Further modifications may include changing the surface profile, the rim or edges, the surface material as well as adding other objects to simulate the antenna environment, investigating 

 

 

Near-field and far-field analysis in GRASP

TThe algorithms available for radiation pattern analysis applies equally well to field points in the far-field of the antenna as to points very close. In addition to presentation of standard far-field pattern cuts and contours, it is therefore also possible to inspect the near-field, for example to judge the planarity of an antenna's aperture field, or to visualize the field from one antenna on surrounding objects, antenna towers, etc.
