Description

 
 
 

POS

With optimum speed and performance, POS is tailored to provide the most accurate and efficient contoured beam optimization of shaped-surface or multi-feed reflector antennas. POS is used for:

 

Features

      Various surface shaping expansion functions
      Control of maximum surface curvature for manufacturability
      Consideration for manufacturing-imposed constraints in the design phases
      CAD export of shaped reflector surface
      Single, dual or multi reflector shaping

 

 
 
 
 
 
 
 

Advanced minimax optimization algorithm

The minimax goal is very useful for most design work because it relates directly to the design requirements. A least-squares optimization is also available and may be convenient for other design criteria or for obtaining a good starting point for minimax optimization. The algorithms allow constraints imposed on the optimization. This includes restricting the surface curvature and total surface deviation, feed displacements and orientations, and the allowed range of array excitation coefficients.

 

Surface constraints

Thermal distortions and different types of manufacturing constraints can be included in the optimization for limiting e.g. surface curvature or feed displacement. Image on the right-hand side illustrates reflector shaping with and without curvature constraints.

 

Optimization of single, dual and multiple reflectors

Single, dual or multiple reflector systems can be optimized and various scattering obstacles can be included. Tools for coverage definition and display of the final results are included in the software. Very special reflectors for e.g. radiating a cosecant-square beam can also be optimized, see figure below. 

 

Optimization of reflectors and arrays

POS features array optimization, even in combination with reflector shaping. The array may contain subarrays in multiple layers for which power division and individual excitations may be optimized.

 

 

Values

      Tailored minmax optimizer ensures extremely fast reflector design
      Highly accurate analysis during optimization
      Thoroughly tested by the space industry for decades
      Compatibility with GRASP
      De facto industry standard for contoured beam reflector antenna design
