IMPROVEMENTS AND CAPABILITY EXTENSION FOR THE IONOSPHERIC RESEARCH AIRCRAFT

Abstract

Means are described for reducing precipitation static interference on a KC-135 aircraft equipped with a refueling boom and with fixed-wire and other special HF antennas. A complement of ortho-decoupled dischargers is recommended, and special precautions to be observed in the design of antenna housings and fittings are discussed. Improvements in the electrical design for an airborne ionospheric-sounder receiving-antenna system for the 2-to-25 megacycle range are described. Single-turn, balanced ellipticalloop antennas with tuners and preamplifiers operating throughout the frequency range were designed for installation in the wing tips of the aircraft. A balanced triangular p was designed for installation in the nose radar bay. In addition, a method of determining the gain of a three-wire transmit-receive antenna on the KC-135 aircraft is described. A summary of studies of a new method of determining the properties of the lower inosphere from airborne measurements is given. (Author)
