Hi Marc,

I am new geopsy user. I would like to ask you an issue in my FK analysis.
Why my both CVFK and HRFK analyses using Test button cannot produce a clear pattern as shown in your online manual to obtain propagation azimuth of the wave? See the attached screen shots.

FYI, I am using circular hexagonal array with radius 50 meter with one instrument in the centre.

Hello user,

this is due to spatial aliasing, maybe your array has a geometric, so you have ambiguety in the range of the wavenumber resolution of your array.

Try to analyze your data in the closest period 2pi/Dmax
