Algorithm 1 Algorithm for DPD-TVD

1:Define the area in which the emitter may exist and determine an appropriate location grid ${\mathbf{p}}_i$, $i=1,\cdots ,M$. 2:for $i=1$ to M do 3: Set $\mathsf{\Theta }\left({\mathbf{p}}_i\right)=0$ 4: for $k=1$ to K do 5:  for $l=1$ to L do 6:   Evaluate ${\tau }_{l,k}\left(t\right)$ 7:   Evaluate ${\mathbf{D}}_{l,k}$, ${\mathbf{F}}_{l,k}$ 8:  end for 9:  Evaluate ${\overline{\mathbf{Q}}}_k$ and ${\mathbf{V}}_k$ according to (16) 10:  Let $\mathsf{\Theta }\left({\mathbf{p}}_i\right)=\mathsf{\Theta }\left({\mathbf{p}}_i\right)+{\lambda }_{max}\left\{{\overline{\mathbf{Q}}}_k\right\}$ 11: end for 12:end for 13:Output: Find the grid point for which $\mathsf{\Theta }\left({\mathbf{p}}_i\right)$ is largest. This point is the estimated position of emitter $\widehat{\mathbf{p}}$. 14:End
