Radar system and method for de-icing its parabolic-cylindrical reflector

Abstract

A ground-based radar system (1) for observing orbiting space objects (A), the radar system (1) comprising at least one incident electromagnetic wave transmitting antenna (2) (S) and at least one parabolic-cylindrical reflector (6), the parabolic-cylindrical reflector (6) being fixedly mounted and comprising an external reflective surface (7) adapted to concentrate the incident electromagnetic waves (S) into a beam with a predetermined pointing direction (D), the external reflective surface (7) being exposed to the weather, the radar system (1) comprising at least one de-icing fluidic network (10) extending under the external reflective surface (7) of the parabolic-cylindrical reflector (6), the de-icing fluidic network (10) being controllable between an inactive (OFF) mode and an active (ON) mode,in which a de-icing fluid (F10) circulates in the de-icing fluid network (10) to de-ice the external reflective surface (7) so as to maintain the determined pointing direction (D).
