Classes

BeamBase

A base class for holding and providing information about beams.

BeamFormed

Provides beam information, given the footprint specification

BeamSinglePorts

Provides beam information for single port beams

Functions

get_port_positions()

class aces.beamset.beambase.BeamBase(num_beams=0, offsets_rect=None)[source]

Bases: object

A base class for holding and providing information about beams. The subclasses in mind are BeamFormed and BeamSingleports.

Parameters:

  • num_beams (int) – number of beams

  • offsets_rect (numpy.ndarray of dimension (num_beams, 2)) – rectangular offsets in l,m about antenna boresight
