What frequency does the Sentinel radar interrogate at?

The Sentinel radar interrogates at a frequency of 1030 MHz, which is utilized for its operational capabilities. This frequency is integral to the radar's function as it facilitates effective identification and tracking of aerial targets. The choice of 1030 MHz allows for a balance between range and resolution, ensuring that the radar can accurately detect and classify various aircraft within its operational theater.

Using this frequency also aligns with industry standards for secondary surveillance radar systems, which often utilize similar bands for communication and interrogation purposes. The specific design of the Sentinel system, including its algorithms and signal processing capabilities, is optimized for this frequency to enhance its detection performance and reduce susceptibility to interference. This makes it a critical element in the overall air defense strategy, as it provides reliable and timely information about potential threats in the airspace.
