IEEE 686-2008 - IEEE Standard Radar Definitions

Standard Details

Revision of IEEE Std 686-1997. This standard is devoted to providing radar definitions. The standard includes terms formerly found in IEEE std 172-1971, IEEE Standard Definitions of Navigation Aid Terms, with the exception of a few terms that are common in both fields, and new and updated terms. IEEE std 172-1983 was withdrawn in 1983. As radar technology and literature evolve, new terms will be added and obsolete terms deleted.

Active Projects	Active P521 - Standard Letter Designations for Radar-Frequency Bands 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. Radar operation at frequencies higher than 300 GHz is addressed.
Existing Standards	Active 521-2002 - IEEE Standard Letter Designations for Radar-Frequency Bands 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 otherre 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.
