Gpfksimulator

Interest

gpfksimulator is intended to be an educational tool. It is a graphical interface displaying the array response function for a superposition of multiple plane waves crossing some given array geometry.

Usage

gpfksimulator after startup

When starting gpfksimulator a file borwser will and you are requested to locate a multi-column ASCII file containing position coordinates of an array setting. As described in warangps section on loading coordinates a flexible parser will allow you to adjust to many different ASCII file formats.

As in warangps, the array response function will be immediately computed and displayed, however, this time not for a vertical incident plane wave (impinging on the array configuration from below with ${\vec {k}}=0$), but for a plane wave with parameters as given in the first table line. On default, a harmonic signal propagating at a wave speed of 300 m/s at a signal frequency of 1 Hz and a propagation direction of $0^{\circ }$.
