Which system frequency is generally associated with A9 operations?

The correct answer, 45 KHz, is associated with A9 operations, which refer to specific communication or radar functions in tactical environments. This frequency is crucial for achieving the operational range and data transmission characteristics that A9 operations require. At 45 KHz, the system can effectively transmit signals that can be utilized in various radar systems or communication equipment intended for real-time data exchange in maritime operations. This frequency provides a balance between range and resolution, allowing for reliable detection and tracking of targets.

Understanding radar frequency assignments is vital, as different operations utilize different frequency bands depending on their specific technical requirements. In the case of A9 operations, the choice of 45 KHz enables modulation techniques that enhance performance in the intended operational scenarios.
