Radar systems operate in frequency bands that since World War II have been identified by letter designations. To recognize and preserve accepted usage, the proposed revision would re-affirm the letter designations for radar, revising the current standard to update it regarding current International Telecommunication Union (ITU) radar band allocations and comments. No change in scope from the current standard is anticipated. The purpose of the proposed project is to reaffirm the use of letter band designations for radar-frequency bands, and to update and correct the notes referring to the letter band designations in this standard. Because of recent changes in the ITU regulations, some of the notes need to be updated, and changed to correctly reflect the current frequency allocations. No change in purpose from the current standard is anticipated. Revision Standard - Superseded. 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 V and W to a portion of the millimeter wave region while retaining the previous letter designators for frequencies. The current (2002) revision keeps the same letter band designations, includes a change in the definition of millimeter wave frequencies to conform to the ITU designation, and revises the notes to Table 1. Table 1 has been modified for international applications by including Regions 1 and 3 in addition to Region 2.
