Revision Standard – Active – Draft.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 band designations of other microwave frequency users. This standard relates the letter terms in common usage to the frequency ranges that they represent. The 1984 revision defined the application of the letters V and W to a portion of the millimeter wave region while retaining the previous letter designators for frequencies. The 2002 revision included a change in the definition of millimeter wave frequencies to conform to the ITU (International Telecommunication Union)designation and revised the notes to Table 1. The current (2019) revision keeps the same letter band designations but adds a “THz” band in recognition of the growing development of echolocation systems and associated technology in the region 300 GHz to 1000 GHz. Table 1 has been modified accordingly and also updated to conform to the latest ITU (2016) designations.
