W band

From Wikipedia, the free encyclopedia

NATO Radio bands A B C D E F G H I J K L M

IEEE Radio bands G P L S C X Ku K Ka V W

The W band of the microwave part of the electromagnetic spectrum and ranges from 75 to 111 GHz. It sits above the U.S. IEEE designated V band (50–75 GHz) in frequency, yet overlaps the NATO designated M band (60–100 GHz). The W band is used for millimeter wave radar research, military radar targeting and tracking applications, and some non-military applications.

A number of Passive MMW cameras are available for Concealed Weapons Detection operating at 94 Ghz. A frequency around 77 GHz is used for automotive cruise control radar. The atmospheric radio window at 94 GHz is used for imaging mm-wave radar applications in astronomy, defense, and security applications.
