    摘要: PROBLEM TO BE SOLVED: To provide a radar return processing system and a method.
    SOLUTION: A radar return processing system and a method are operable to process radar information when an installation vehicle 122 operates in proximity to a surface area of interest. An exemplary embodiment reduces the energy of an output pulse emitted from a radar system 410, receives a plurality of radar echoes from a plurality of objects that reflect the reduced energy output pulses emitted from the radar system 410, determines a surface area of interest based upon at least a current location of the installation vehicle 122, and filters the radar echoes generated by objects to remove them that are located outside the surface area of interest. Optionally, some of the systems and methods may reduce a sweep range of an antenna on which the reduced energy output pulses are emitted.

    摘要: 橋梁、高架道路などの構造物などの二次元または三次元に広がりを持つ観測対象の振動を観測し、その観測結果を可視化する。観測対象(8)に向けて送信信号を送信する送信手段(10)と、観測対象からの反射波を複数の受信アンテナ(20)で受け、受信アンテナ毎に受信信号を生成する受信手段(12)と、受信信号間の位相差からアンテナ面に対する反射波の位相面を求めて反射波の到来方向および信号強度を同定し、その特定方向からの反射波の位相変動を算出し、観測対象またはその特定部位の振動を表す観測信号を生成する信号処理手段(14)を備える。さらに、斯かる干渉型振動観装置(4)が振動や動揺を有するプラットフォーム(6)に搭載された場合、観測対象(8)の振動を表す観測データで画像を生成し、この画像から固定点を決定し、該固定点の振動解析によりプラットフォーム(6)の振動を算出し、該振動を観測データから除去する。
