vsh

pylayers.antprop.antvsh.vsh(A, dsf=1)

A dsf : in

downsamplig factor

This function calculates the Vector Spherical Harmonics coefficients It makes use of the spherepack function vha

m : phi longitude n : theta latitude

Antenna pattern are stored (f theta phi) Coeff are stored with this order (f , n , m )

The vsh coefficient are organized differently should be better for compression along frequency axis

A : antenna dsf : int

down sampling factor ‘default 1’
