SART operates in which frequency band?

SART operates in which frequency band?

• A. 9 GHz
• B. 2.4 GHz
• C. 30 Hz
• D. 518 kHz

Answer: (A)

SART is designed to respond to radar interrogations using the 9 GHz range, placing it in the X-band so standard maritime radar can detect its beacon. This frequency allows the radar’s signal to be effectively received and the SART’s response to produce a distinctive pattern that helps rescuers determine position and bearing. The other options are outside the typical radar-based interrogation band (2.4 GHz is a consumer wireless band, 30 Hz is far too low for RF, and 518 kHz is an LF band), so they wouldn’t provide reliable detection by standard radar systems.
