What equipment is used to control and monitor the SENTINEL radar and provides visual display?

The Enhanced Radar Control Terminal (eRCT) is specifically designed to control and monitor the SENTINEL radar system, providing operators with the necessary tools to visualize radar data effectively. This equipment integrates advanced software and hardware that enables real-time processing and display of radar information.

One of the eRCT's primary functions is to translate radar signals into actionable intelligence, allowing operators to interpret tracking information and respond to aerial threats promptly. The visual display it offers is essential for situational awareness, facilitating better decision-making during air defense operations.

While the other options might relate to radar systems and data management in some capacity, they do not specifically serve the integral role of controlling and displaying SENTINEL radar outputs. This distinction makes the eRCT the most appropriate choice for the task described in the question.
