During what operation is azimuth positioning controlled by the RSC?

Azimuth positioning controlled by the Radar System Controller (RSC) occurs during a STOP SECTOR SCAN operation. This scenario is specific to situations where the radar needs to halt its sweeping motion and focus on a particular sector of interest.

During a STOP SECTOR SCAN, the RSC retains control over the azimuth positioning, allowing for precise tracking or observation of specific targets within the designated sector. This controlled positioning helps in maintaining target fixation, ensuring accurate monitoring and data collection. The RSC plays a pivotal role here by stabilizing the radar's view while the system collects relevant information.

In contrast, other operations like continuous tracking and target acquisition typically involve different modes of radar operation and may not require fixed azimuth positioning in the same controlled manner. Wide area search generally involves a sweeping motion to cover larger areas, which wouldn't necessitate the concentrated control that a STOP SECTOR SCAN provides. Thus, the specific functionality of the RSC in STOP SECTOR SCAN is crucial for effective azimuth positioning control.
