The remote sensing community regularly uses letter designations for frequency bands whose origins can be traced back to the U.S. military during World War II. These designations were used to keep the frequencies of radar operations a secret throughout the war and afterward. This secrecy ended and some degree of global standardization was achieved during the International Telecommunication Union (ITU) meeting of 1959 in Geneva. The Institute of Electrical and Electronics Engineers (IEEE) has been maintaining the Standard Letter Designations for radar-frequency bands since 1976, which were revised most recently in 2002 (see Table B.1). The letter designations are assigned to frequency bands that are spaced at intervals of about an octave within the frequency range from 3 MHz to 300 GHz. Table B.1 also provides the comparison of the IEEE Letter Designations with the ITU bands and their nomenclature.Suggested Citation:'Appendix B: IEEE Standard Letter Designations for Radar Bands.'

NOTES:
1. Filezilla 3.46.3 portable. These International Telecommunication Union (ITU) frequency allocations are from the table contained in Article S5 of the ITU Radio Regulations, 2002 edition, reaffirmed in 2009 (see https://standards.ieee.org/findstds/standard/521-2002.html). The ITU defines no specific service for radar, and the frequency assignments listed are derived from those radio services that use radiolocation. The frequency allocations listed include those for both primary and secondary service. The listings of frequency assignments are included for reference only and are subject to change.
2. The specific frequency ranges for radiolocation are listed in the National Telecommunications and Information Administration (NTIA) Manual of Regulations & Procedures for Federal Radio Frequency Management, Chapter 4. The NTIA manual (known as the Redbook) can be downloaded from http://www.ntia.doc.gov/osmhome/redbook/redbook.html.
3. There are no official ITU radiolocation bands at HF. So-called HF radars might operate anywhere from just above the broadcast band (1.605 MHz) to 40 MHz or higher.
4. Frequencies from 216-450 MHz were sometimes called P-band.
5. The official ITU designation for the ultra high frequency band extends to 3000 MHz. In radar practice, however, the upper limit is usually taken as 1000 MHz, L- and S-bands being used to describe the higher UHF region.Suggested Citation:'Appendix B: IEEE Standard Letter Designations for Radar Bands.'

6. Sometimes included in L-band.Ieee Green Book
7. Designated for aeronautical navigation, this band is reserved (with few exceptions) exclusively for airborne radar altimeters. 8. The frequency range of 24.65-24.75 GHz includes satellite radiolocation (Earth to space only).Ieee Brown Book
9. The designation mm is derived from millimeter wave radar and is also used to refer to V- and W-bands, and part of Ka-band, when general information relating to the region above 30 GHz is to be conveyed. Apeaksoft android toolkit 1.1.18.
