Cover member having plurality of faces, and radar apparatus provided with the cover member

Abstract

A radar apparatus includes transmitting means, receiving means, target detection means, and a cover member. The cover member is positioned opposite at least one of the transmitting means and the receiving means, such as to cover at least one of the transmitting means and the receiving means. The cover member is provided with a first face which is positioned opposite at least one of the transmitting means and the receiving means, and a second face which is on an opposite side from the first face and is not parallel to the first face.

1 . A radar apparatus comprising:
 transmitting means for transmitting probe waves,   receiving means for receiving incoming waves,   target detection means for detecting targets that are origins of the incoming waves, based on results of transmitting the probe waves and receiving the incoming waves, and   a cover member positioned opposite at least one of the transmitting means and the receiving means, such as to cover at least one of the transmitting means and the receiving means, wherein   the cover member includes:   
       a first face which is positioned opposite at least one of the transmitting means and the receiving means, and
 a second face which is on an opposite side from the first face, and which is not parallel to the first face. 
 
     
     
         2 . The radar apparatus according to  claim 1 , wherein the first face comprises:
 a transmitting opposing face positioned opposite the transmitting means, and   a receiving opposing face positioned opposite the receiving means; wherein   the transmitting opposing face and the receiving opposing face are not parallel to one another.   
     
     
         3 . The radar apparatus according to  claim 2 , wherein at least one of the transmitting opposing face and the receiving opposing face is a curved surface. 
     
     
         4 . The radar apparatus according to  claim 2 , wherein at least one of the transmitting opposing face and the receiving opposing face is a planar surface. 
     
     
         5 . The radar apparatus according to  claim 2 , wherein the radar apparatus is installed on a mobile body and
 the transmitting means is positioned at a lower side than the receiving means, along a vertical direction of the mobile body, and   a thickness between the transmitting opposing face and the second face increases in accordance with increased proximity to the lower side, along the vertical direction.   
     
     
         6 . A cover member provided in a radar apparatus comprising transmitting means for transmitting probe waves, receiving means for receiving incoming waves, and target detection means for detecting targets that are origins of the incoming waves, based on results of transmitting the probe waves and receiving the incoming waves, wherein
 the cover member is positioned opposite at least one of the transmitting means and the receiving means, such as to cover at least one of the transmitting means and the receiving means;   characterized in that the cover member includes:   a first face which is positioned opposite at least one of the transmitting means and the receiving means, and   a second face which is on an opposite side from the first face, and which is not parallel to the first face.
