Well it's been over a decade since I touched signals calc, but it's obviously a cosine sweep. Your spectrogram looks like
w = 3; % just a guess
t = linspace(0,w,1000);
f = linspace(0,w,1000).';
s = cos(2*pi*f.*t);
pcolor(t,f,s)
shading flat
So maybe you could start with that and work back to time domain.
