¿µ¹®³»¿ë¿ä¾à The Standard Letter Designations for Radar-Frequency Bands was first issued in 1976 and was written to remove the confusion that developed from the misapplication to radar of letter common usage to the frequency ranges that they represent. The 1984 revision defined the application V and W to a portion of the millimeter wave region while retaining the previous letter designators for frequencies below the millimeter region. This revision keeps the same letter band designation, and revises the notes to Table 1. Table 1 has been modified for international application by including Region 1 and 3 in addition to Region 2.
