Abstract:

The report summarizes the design of a communications circuit using the man-made ionospheric scatterers and the characteristics of VHF signals propagated over such a circuit. It represents a compilation of experimental data obtained during field exercises in which communications were established between terminals separated 1400 km and 2200 km. The scattering cloud was located 1000-1200 km from both transmitter and receiver terminals. The report summarizes the requirements of an ionospheric heater and describes the characteristics of the disturbance itself. These characteristics include observed radar cross section as a function of time of day, amount of heater radiated power, and heater modulation.
