Current airborne radars of the world in the International Radar Directory CD-ROM

The International Radar Directory CD-ROM (IRD) resulted from a twenty-year collection effort by this author of open information on radars of the world. That effort identified some 9,800 radars; however, most of those numbers are no longer in use. The production IRD contains technical information on 674 current radars. Radar functions (applications) now include some 50. This paper presents a review of current airborne radars of the world and illustrates how the IRD can be used.
