Radar Contact is the condition that exits when an aircraft has been identified on the radar display and radar services are being provided. 雷達已識別是指一架飛機已經(jīng)在雷達上被雷達識別并且即將被提供雷達服務(wù)的情形。
An aeroplane shrouded in such kit might be invisible to the human eye but it would be picked up readily by radar, which operates at radio wavelengths. 用這種東西罩住的飛機對于人眼來(lái)說(shuō)可能是隱形的，卻會(huì )輕而易舉地被雷達識別，因為雷達是工作在無(wú)線(xiàn)電波段的。
