DISPERSIVE CHARACTERISTICS OF THE IONOSPHERE.
Abstract
The experiments to be performed are outlined, and the over-all block diagrams for the three transmitter sites and the common receiver site are discussed. Progress on each of the new equipments being supplied is then discussed. The effects of the site terrain on HF antenna patterns are presented. In particular, an analysis of diffraction patterns over mountainous terrain is detailed. The progress on the design of a high dynamic range, dual-channel HF receiver is given. Special emphasis is on the RF filter bank design. The design details of a digital processor to convert the analog information into digital form and record it on magnetic tape are discussed. The design of the mode processor, which provides for temporal sampling of the various received signals, is presented. Modifications and additions to the existing Phantom pulse compression system and azimuthal angle of arrival equipment are discussed. The specifications of the various equipments being purchased from subcontractors are described. These equipments include Loran C absolute timing systems, Granger ionospheric sounders, and test and communications units.
