   The term "radar netting" (fig 43) describes the process by which track data derived from several additional or remote radars are gathered at a single center to produce an integrated set of meaningful target information which can be distributed to all AD elements concerned. … Radar netting can provide concurrent coverage of a selected area by more than one radar.

Etymology 2

From Middle English netting (“urine”). Further etymology unclear. Perhaps borrowed from Middle Low German nattinge (“wetness”), or derived from Middle Low German nette (“wetness, urine”), netten (“to wet, urinate”). Alternatively, perhaps from an unrecorded Old English *nettan (“to wet”), from Proto-West Germanic *nattjan (“to wet”), related to Middle Low German netten (“to wet, urinate”), Dutch netten (“to wet”), German nässen (“to wet”).
