Hello !
If you want your function to be integrable and so on, you have to use UnitStep :
g[t_]:=UnitStep[t,1-t]t+UnitStep[3-t,t-1](1.5-.5t)
In[4]:=
Plot[g[t],{t,-4,4}]
And then, just use "FourierTransform".
But have a look at the Help browser to look what parameters you wish.
Default : ff[Ï?_] = FourierTransform[g[t], t, Ï?]

How to compute in Mathematica fourier transform of function:
t ,0=< t =<1
g(t)=
1.5-0.5t , 1< t =<3
to tell the truth i dont even know how to make Mathematica print that
function.
