英語でBACK SCATTERはどんな意味ですか？
後方散乱
物理学では、後方散乱は、波、粒子、または信号がそれらが来る方向に戻ることを反映しています。 鏡のような鏡面反射とは対照的に、散乱による拡散反射である。 後方散乱は、天文学、写真、および医療用超音波検査において重要な用途を有する。
英語辞典でのback scatterの定義
辞書の後方散乱の第1の定義は、音波またはX線、またはアルファ粒子などの粒子または放射線が、通過する媒体の原子によって逆方向に散乱することである。 後方散乱の他の定義は、散乱された放射または粒子である。 後方散乱はまた、非常に長距離のレーダーが地球の湾曲によって隠されたターゲットを見つける技術でもあります。 レーダービームは、対流圏の下面からターゲット上に反射され、同様に反射された戻りビームが測定される。
