Abstract
Description
本発明の目的は、先行するアンテナ・システムより品質が高いレーダ信号を与えるアンテナを生み出すことである。本発明によって、送信機アンテナから受信機アンテナへの直接波を著しく抑制し、二重パルスをほぼ完全に無くし、そしてアンテナと地表面の間で多重を著しく抑制することが可能になる。
一実施形態によれば、2つのアンテナ装置の間の垂直平面における角度(α)は、前記接地平面を互いに機械的に接続する非導電性ヒンジを使用して、調節することができる。
ここで、添付図面を参照して、本発明をより綿密に述べる。
Claims (8)
- 地中レーダ用のアンテナ・システムであって、2つのシート状のアンテナ装置を備え、該2つのアンテナ装置は、少なくとも1つの送信機アンテナ(1)と少なくとも1つの受信機アンテナ(2)とをそれぞれ含み、各アンテナ装置におけるアンテナ(1、2)は、レーダ吸収材料(4)の層の下側に位置する電気絶縁シート担体(3)上に金属構造物を塗布することによって形成されるモノポールからなり、材料層の上面が、金属製接地平面(5)によって被覆される、アンテナ・システムにおいて、
該アンテナ装置は、該アンテナ装置が通常動作中に先端を地面(10)へと下方に向けた状態でV字形状くさびを形成するために、給電点(6)から下方に傾斜する姿勢を有するように配置され、接地平面(5)は、互いに電気的に接続されていないことを特徴とする、アンテナ・システム。 - 前記アンテナ(1、2)は、本質的にV字形状である、請求項1に記載のアンテナ・システム。
- 前記レーダ吸収材料(4)は、1つまたは複数の層からなる、請求項1または2に記載のアンテナ・システム。
- 前記2つのアンテナ装置の間の垂直平面における角度(α)が、前記接地平面(5)を互いに機械的に接続する非導電性ヒンジ(9)を使用して、調節することができる、請求項1乃至3のいずれか一項に記載のアンテナ・システム。
- 前記アンテナの端末点が、抵抗器(7)およびスペーサ(8)を介して前記接地平面(5)に接続される、請求項1乃至4のいずれか一項に記載のアンテナ・システム。
- 前記送信機アンテナ(1)の端末点は、前記受信機アンテナ(2)の前記端末点に向けて方向付けられる、請求項1乃至5のいずれか一項に記載のアンテナ・システム。
- 複数の送信機アンテナ(1)および複数の受信機アンテナ(2)を備え、
前記2つのアンテナ装置の間で対称軸に沿って分散されるアンテナの線形アレイを形成する、請求項1乃至6のいずれか一項に記載のアンテナ・システム。 - シート担体(3)は、好ましくはガラス繊維基板からなる積層板、特に回路基板積層板である、請求項1乃至7のいずれか一項に記載のアンテナ・システム。
