Over a period of time these frequencies and their associated letter-band designations have been fixed by usage. In order to recognize and preserve accepted usage, this standard defines the letter-band nomenclature to be used as a convenience for describing the frequency in which radar operates. It should be cautioned that these are not a substitute for the specific frequency limits of a radar, nor is it meant that these letter bands be applied to other than radar. 517 $aIEEE Std 521-1976 606 $aTracking radar 606 $aRadar$xInterference 615 0$aTracking radar. 615 0$aRadar$xInterference. 676 $a621.3848 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910136386603321 996 $aIEEE Std 521-1976$93646202 997 $aUNINA LEADER 00724nac# 22002051i 450 001 UON00495538 005 20231205105351.470 100 $a20190610f |0itac50 ba 102 $aAT 105 $a|||| ||||| 110 $ab|||||||||| 200 1 $aComputerwelt 210 $aWien$cInfo Technologie 463 1$1001UON00495535$12001 $aLexikon der aktuellen IT-Fachbegriffe$eRund 1.500 aktuelle Fachbegriffe aus dem Bereich Informationstechnik$f[Hrsg.
