Derive an expression for the ambiguity function of a V-LFM waveform, illustrated in the figure below. In this case, the overall complex envelope is \[
\tilde{x}(t)=\tilde{x}_{1}(t)+\tilde{x}_{2}(t) ; \quad-Twhere \[
\begin{array}{cc}
\tilde{x}_{1}(t)=\frac{1}{\sqrt{2 T}} \exp \left\{-\mu t^{2}ight\} ; & -T\tilde{x}_{2}(t)=\frac{1}{\sqrt{2 T}} \exp \left\{\mu t^{2}ight\} ; & 0\]
