Title
(EN) BOLOMETRIC DETECTOR WITH ANTENNA
(FR) DETECTEUR BOLOMETRIQUE A ANTENNE
Abstract
(EN)
The invention concerns a bolometric detector comprising a receiver antenna (2a, 2b, 2c, 2d) to receive electromagnetic waves and a resistive load to convert the power of the electromagnetic waves into heating capacity. The resistive load is the antenna load resistance. The invention is particularly useful for detecting objects in all weather conditions (rain, fog, smoke and so on).
(FR)
L'invention concerne un détecteur bolométriue comprenant une antenne de réception (2a, 2b, 2c, 2d) pour recueillir des ondes électromagnétiques et une charge résistive pour convertir la puissance des ondes électromagnétiques en puissance calorifique. La charge résistive est la résistance de charge de l'antenne. L'invention s'applique plus particulièrement à la détection d'objets dans des conditions 'tout-temps' (pluie, brouillard, fumée, etc...).
