| 520 | ⊔ | ⊔ | ‡aInvestigation of ionospheric phenomena over large areas of the world has been pursued by Air Force Cambridge Research Laboratories since 1953 by means of ionospheric sounders carried in large aircraft. Technical details of the first airborne ionospheric sounding system utilizing a modified C-3A Automatic Ionosphere Recorder in a JKC-97 aircraft, are described briefly. Emphasis is given to the limitations and special considerations connected with an airborne ionospheric sounder such as adequate antenna, types of interference, power, effects of temperature and vibration, and peculiarities of airborne data. Mutual operation with other projects on the aircraft conducting various photometric measurements, is discussed in regard to the severe rf interference produced by the ionospheric sounder. (Author). |
