This standard is published for the purpose of promoting clarity and consistency in the use of radar terminology. The definitions represent the consensus (reached after several rounds of review, comment, and revision) of a panel of radar experts, including authors of several books on radar. It is intended that these definitions shall serve as a guide to standardization of meanings.

686-2017
IEEE Standard for Radar Definitions
The promotion of clarity and consistency in the use of radar terminology is the purpose of the definitions provided in this guide. The consensus of a panel of radar experts are represented in the definitions herein.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
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 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.
686-1997
IEEE Standard Radar Definitions
Definitions for the purpose of promoting clarity and consistency in the use of radar terminology are provided. The definitions represent the consensus of a panel of radar experts.
686-2008
IEEE Standard Radar Definitions
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 IEEE std 172-1983 was withdrawn in 1983.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.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
686-1990
IEEE Standard Radar Definitions
Definitions for the purpose of promoting clarity and consistency in the use of radar terminology are provided. The definitions represent the consensus of a panel of radar experts.
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
