The present invention relates to a passive microwave detector for a satellite having a fixed reflection plate installed thereon. The passive microwave detector includes: a motor (100) which includes a first rotary shaft (110) extended in the moving direction of the satellite; a first rotary reflection plate (200) which is positioned at a predetermined angle with respect to the ground surface right below, has the center of a first side surface (210) coupled to the first rotary shaft (110) to rotate in order to move the first side surface (210) and a first opposite side surface (220) alternately to the ground surface, enables the first side surface (210) to absorb incident electromagnetic waves, and enables the other first opposite side surface (220) to reflect the incident electromagnetic waves; a secondary reflection unit (300) which reflects the electromagnetic waves entering from the first opposite side surface (220) to a predetermined location; a reception unit (400) which receives the electromagnetic waves reflected from the secondary reflection unit (300); and a fixed reflection plate (500) which is fixed on the upper part of the first rotary reflection plate (200) at a predetermined angle with respect to the ground surface in order to reflect the electromagnetic waves to the first side surface (210) or the first opposite side surface (220).

    본 발명은 고정반사판이 설치된 위성용 수동형 마이크로파 탐측기에 관한 것으로, 위성의 진행방향으로 연장형성된 제1회전축(110)을 포함하는 모터(100), 직하 방향의 지표면과 미리 정해진 각도를 이루고, 제1일측면(210)의 중앙이 상기 제1회전축(110)과 결합하여 회전하여 상기 제1일측면(210)과 제1타측면(220)이 교대로 지표면을 향하며, 상기 제1일측면(210)은 입사되는 전자파를 흡수하고, 상기 제1타측면(220)은 입사되는 전자파를 반사하는 제1회전반사판(200), 상기 제1타측면(220)으로부터 입사되는 전자파를 일정한 위치로 반사시키는 보조반사부(300), 상기 보조반사부(300)에서 반사된 전자파를 수신하는 수신부(400) 및 상기 제1회전반사판(200)의 상부에 지표면과 미리 정해진 각도를 가지고 고정되어 전자파를 상기 제1일측면(210) 또는 제1타측면(220)으로 반사시키는 고정반사판(500)을 포함하여 이루어지는 것을 특징으로 한다.
