far field measurementとは 意味・読み方・使い方

To provide an electromagnetic field measurement method for measuring the strength distribution and the phase distribution of an near-field electromagnetic field close by a measurement object, at high resolution and which is capable of accurate estimation of a far-field normalized values, as compared with those by conventional types.例文帳に追加

被測定物の近傍電磁界の強度分布と位相分布を高分解能で測定し、遠方規格値を従来よりも高精度で推定できる電磁界測定方法を提供することを目的とする。 - 特許庁

The radar cross section measurement method and radar cross section measurement device which use the ground bounce determine the radar cross section in a far-field region by integrating, over the corresponding range of an object to be measured, the scatter source distribution obtained by transforming the scatter electric field values acquired by measuring the object to be measured over the range of predetermined two dimensional angles in the directions Az and E1.例文帳に追加

地面反射を利用したレーダ断面積測定方法および装置において、被測定物ＴをＡｚおよびＥｌ方向に２次元の所定の角度範囲分測定した散乱電界値を変換して得られた反射源分布を、前記被測定物相当の範囲で積算して遠方領域でのレーダ断面積を得る。 - 特許庁

Thus, there is not problem of the difficulty in positioning a measuring point and taking too long a time required for measurement by the conventional means so far manually moving the sensor to a predetermined measuring point, so that the state of the magnetic field generated in a three-dimensional space around the measuring object can be measured accurately and quickly.例文帳に追加

従って、センサを予め決めた測定点に対して手動で動かしていた従来の手段のように、測定点の位置合わせが困難で、測定に要する時間が長くかかり過ぎるという問題がなく、測定対象物周囲の三次元空間で生じている磁界の状態を正確かつ迅速に測定することができる。 - 特許庁
