SART operates in which frequency band?

Explanation:
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.
