\section{Overview}\label{sec:intro}  This document presents a parametric model to help design an Interferometric Array. One aspect of Array Design is the value vs. cost trade-off inherent to many of its parameters. This document describes design parameters in \S~\ref{sec:var} and a set of value objectives for them in \S~\ref{sec:obj}.   A python code that uses these design parameters and value relationships to enable analysis of the Pareto front is introduced in \S~\ref{sec:python}. This code is consistent with Multi-Objective Visual Analytics (MOVA) framework for complex engineered systems  proposed in \cite{mova}. \section{Parameters}\label{sec:var}  This section aims to include all relevant design parameters that might influence the selected performance objectives in \S~\ref{sec:obj}.  \subsection{Antenna Aspects}
