 note = {空港の輻湊の軽減,騒音の軽減のために,多経路又は可変経路の降下路が必要とされるが,それに対して,ドップラ・アレイを用いる試みが欧米で行われている.本論文は,ドップラ・アレイの設計に必要な遠方界の周波数スペクトルの解析を行ったものである.初めに,波源の関数と遠方界との関係及び遠方界の周波数スペクトルの一般式をあげ次に波源の包絡線が,矩形波及びガウス形である場合のスペクトルを求めてある付録では,包絡線が一般の波形の場合も取扱ってあり,更に,波源が連続的に動きながら輻射する場合も取扱ってある., For the countermeasure of the congestion and the noise of airports, the systems of multiple and variable landing path are needed. For the purpose the systems using the doppler array are being tried in Europe and United State. In this paper frequency spectrum of far field radiated by the doppler array are analyzed to help to design the array. The relation between wave source function and far field and general formula of frequency spectrum are described first. And then the spectra of the fields by rectangular and Gauss type modulated wave sources moving point to point and radiating at the points are obtained. The analyses for general wave-type modulated wave source and also for continuously moving and radiating source are described in appendix., 資料番号: SA0124535000},
