Abstract : Two methods of oblique-incidence ionospheric sounding--sweep-frequency cw and pulse--were compared over the 8000-km path from Hawaii to Mass. Three cw frequency sweep rates, 25, 100, and 1000 kHz/sec, were explored at various power levels between 1 and 10,000 w. The pulse sounder employed 100-used, 30-kw pulses at a repetition rate of 50 pulses/sec. The tests were conducted in December 1965. (Author)
