The relativistic effect in Global Navigation Satellite System satellites has two parts, of which the first part is the time dilation due to the shift in the fundamental frequency of the satellite clock. The second part is due to the satellite’s semi-major axis and __________

Match the following SAR sensors to their frequency bands:

\[ \begin{array}{|c|l|c|l|} \hline \textbf{Column I} & \textbf{SAR Sensor} & \textbf{Column II} & \textbf{Frequency Band} \\ \hline P & \text{NOVASAR} & 1 & \text{X-BAND} \\ Q & \text{RISAT-1} & 2 & \text{C-BAND} \\ R & \text{TERRASAR} & 3 & \text{L-BAND} \\ S & \text{ALOS PALSAR} & 4 & \text{S-BAND} \\ \hline \end{array} \]
