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...

Regards.
