Radiometric illumination for short-range radar
Visnyk NTUU KPI Seriia - Radiotekhnika Radioaparatobuduvannia, 2016 The usage of methods and devices of close multichannel location requires usage of illumination devices to increase radio brightness of the research’s object. As a source of radiation apart of traditional noise oscillators, gas-charge tubes can be used, which are not used for regular location.
