Deconvolution / Spectral division (Antenna)

Started by SiFunc December 29, 2011
Hi @ all,

I record a signal with spectrum Sig_Rec(f), via an antenna which has its
own frequency response, A(f). To get rid of the antenna's influence I
perform a spectral division in frequency domain ("deconvolution"):

Sig_True(f) = Sig_Rec(f) / A(f)

Unfortunately by doing the division-process teh result becomes much more
worse than before. Does someone have some ideas how to go on? What can I
do? Maybe I have some division by a very small number which makes the
result unreasonable? Or sth. like this...
