ABSTRACT:
The invention relates to a bolometric detector comprising a receiving antenna (2a, 2b, 2c, 2d) for collecting electromagnetic waves and a resistive load for converting the power of electromagnetic waves into heating power. The resistive load is the load resistor of the antenna.The invention is more particularly applied to the detection of objects in “all-weather” conditions (rain, fog, smoke, etc).
