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.

This usage has continued throughout the years and is now an accepted practice of radar engineers. Radar-frequency letter designations are used for given reasons. The radar letter designations are consistent with the recommended nomenclature of the International Telecommunications Union (ITU). The high frequency (HF) and the very high frequency (VHF) definitions are identical in the two systems. The essence of the radar nomenclature is to subdivide the existing ITU bands, in accordance with radar practice, without conflict or ambiguity.<br />\n \t\t\t\t<br />\n Since World War II, radar systems engineers have used letter designations as a short notation for describing the frequency band of operation. This usage has continued throughout the years and is now an accepted practice of radar engineers. Radar-frequency letter designations are used for the following reasons:<br />\n 1) They provide a convenient method for describing the band in which the radar operates without the need for awkwardly stating the limits of the frequency in numerical terms. For example, it is more convenient to say an L-band radar than a 1215 MHz to 1400 MHz radar.

The letter designations permit this.<br />\n 3) Each radar-frequency band has its own particular characteristics. Thus an X-band radar will be different from an S-band radar. The letter designations are often used in this manner to indicate the particular nature of the radar as it is influenced by its frequency. There are vast differences in characteristics, applications, and environmental constraints which distinguish radars in the different bands. It is the need to communicate concisely the whole set of characteristics which are shared by S-band radar, as distinguished from L-band radar, C-band radar, and the otherres, which requires the established usage of letter designations.
