News Let. 28 May 339 Most of the radio frequency power in the new method is lost, but some is scattered by the lower part of the E region... This portion is received hundreds of miles away by high-gain antennas aimed at the exact spot. The system is called either forward scatter, or FPIS, for forward propagation by ionospheric scatter. 1958Times 8 Nov. 4/7 Assurances that the ionospheric forward-scatter radio station..will not represent a radiation hazard to the public have now been given officially. 1966Electronics 3 Oct. 181 Boelkow has designed a fixed-wing rocket—intended for ionospheric studies—that can be recovered from 48 miles.
