Array structures | Frequency increment sequence |
|---|---|
Phased array (PA) | \(\Delta f \cdot \underbrace {{\left[ {\begin{array}{*{20}c} 0 & 0 & \ldots & 0 & \ldots & 0 \\ \end{array} } \right]}}_{Q}\) |
Uniform linear FDA (ULFDA) | \(\Delta f \cdot \underbrace {{\left[ {\begin{array}{*{20}c} 0 & 1 & \ldots & {q - 1} & \ldots & {Q - 1} \\ \end{array} } \right]}}_{Q}\) |
Linear FDA with Log variation frequency increment (LogFDA) | \(\Delta f \cdot \underbrace {{\left[ {\begin{array}{*{20}c} 0 & {\log \left( 2 \right)} & \ldots & {\log \left( q \right)} & \ldots & {\log \left( Q \right)} \\ \end{array} } \right]}}_{Q}\) |
Linear FDA with random frequency increment (RFDA) | \(\Delta f \cdot \underbrace {{\left[ {\begin{array}{*{20}c} 0 & {{\text{rand}}\left( Q \right)} & \ldots & {{\text{rand}}\left( Q \right)} & \ldots & {{\text{rand}}\left( Q \right)} \\ \end{array} } \right]}}_{Q}\) |
