When a radar pulse strikes the SART, it turns on automatically if the pulse has what characteristic?

SARTs are designed to respond to radar interrogations in the X-band, which uses a wavelength of about 3 centimeters. When a radar pulse at that wavelength strikes the SART, it automatically turns on and transmits a distinctive beacon pattern that shows up clearly on the rescuing vessel’s radar, helping locate the survivor. Wavelengths of 1 cm, 5 cm, or 10 cm correspond to different radar bands outside the X-band, and those pulses wouldn’t trigger the SART, which is why 3 cm is the correct characteristic.
