Phased Array Element Configuration File

Enables you to define the number of elements and their placement. Lines in the file starting with a hash symbol (#) are treated as a comment line.

Keyword	Description
AsciiDataElementPattern v1	Indicates the data format and version of the data format. This keyword is required and must be the first line in the file.
Element Positions	One element position per line, specified as a space-separated pair of numbers: x y, where x and y are in number of wavelengths (lambdas). Elements specified in the file are assigned an ID starting with 0 for the first x,y pair read in and ending with an ID of N-1, with N-1 for the Nth x,y pair.

Element Configuration File Sample Format

Following is an example file for a 2x3 element with rectangular lattice configuration:

# This is a comment line
# Sample of a 7-element ULA with 0.5 spacing.
# First non-comment line is a tag indicating the type of file followed by the file format version.
# Remaining non-comment lines are positions of the elements with following format:
#   <x0> <y0>  where xi yi represent position of ith element in wavelenghts (lambdas) and 0,0 is at mechanical boresight.

#   <x1> <y1>

#   ...   ...

#   <xi>  <yi>
