Description
この要件は、データ記憶要求に負担をかけ、さらに、こうした多量のデータを迅速に移動させるのは困難であり得るので、走査速度に実際的な制限を課すことがある。
の波形が記録されなければならない。さらに、3つの素子のそれぞれは、一度に作動されなければならない。3つの探触子場所のための全てのデータを収集するために、合計9回の素子作動が必要とされ、且つ、18個の波形を収集しなければならない。
このように、32素子アレイが使用され、100箇所のデータ地点が走査線に沿って獲得される状況においては、3696個の波形のみが収集される必要があり、131回の素子作動のみが必要とされる。これは、データの冗長性を利用する本願で特許請求される発明を使用しない場合の、3200回の作動から収集される必要のある(32×33/2)×100=52800個の波形に引けを取らない。
作動の回数(ピッチ・キャッチ)=2(k+m−1)−1、及び
収集される波形の数(ピッチ・キャッチ)=k(2m−1)+(m−1)2
波形の数(2次元アレイ)≒(k+n−1)・(l+m−1)・[n・m+(n−1)・(m−1)]
である。k×lグリッド全体の完全な再構成を実現するために、[(n・m)+(n−1)・(m−1)]よりも少ない波形がグリッドの辺付近の走査位置で収集される必要があるので、この近似式は、必要とされる波形の総数を過大に見積もるものである。しかし、データ記憶要件を削減するために、この新規の収集方法を使用する利点を説明するには十分である。16×8アレイの実例に戻ると、これは、8回の作動のみが各探触子場所で必要とされ、且つ、233個の波形が記憶される必要があることを意味している。探触子場所と同じ100×100アレイの場合、これは、おおよそ(115・107・233)・1000バイト=おおよそ3GBの総計データ記憶となり、当分野で現在知られた技術を使用して容易に実施可能である。
個の波形が記録されなければならない。あらゆる走査位置での全ての行列を埋めるのに必要とされる全ての波形を記録するために、余分な波形が、公称の走査グリッドを越えた位置で記録される必要がある。k×l位置全体の走査に必要とされる波形の総数の概算は、
である。この概算は、公称範囲kを越えた位置で収集される必要のある波形の数の減少について考慮しないので、いくらか控えめである。100×100の走査位置を有する16×8アレイの実例に戻ると、記憶される必要のある総計データは、およそ(115・100・996)・1000バイト=11.45GBである。これは、やはり、標準的な収集方法を使用して必要とされる82GBの記憶要件と比べるとかなりの改善である。
