cyclic coordinatesとは 意味・読み方・使い方

From a plurality of reference positions R on known three-dimensional coordinates above the ground or in the ground, cyclic reference signals fr modulated by identification code strings P of strong autocorrelation but of weak cross correlation are transmitted on a rotating magnetic field 3 of a prescribed carrier frequency fc into the ground 2.例文帳に追加

地上又は地中の既知三次元座標の複数の基準位置Ｒから、自己相関が強く相互相関が弱い識別符号列Ｐで変調された周期性基準信号frを、所定搬送周波数fcの回転磁界３に乗せて地中２へ発信する。 - 特許庁
