The applet simulates how the placement of the antennas affects the uv-coverage of a given array and illustrates the fourier transform relationship between the accumulated radio visibilities and the resultant image.
This applet is focussed on four "panels" which represent (clockwise from top right), the placement of the antennas on the ground, the uv-coverage that would result from that placement, the fourier transform of the image (which may be masked by the uv-coverage) and the image itself (either initial or measured). Various widgets around the outside of these panels allow the control of various parameters.
