| dc.description.abstract | The design, construction, and testing of a narrow-band FM system for VHF E-scatter communications between Rankin Inlet, N.W.T. and Park Site, Saskatchewan are described._ A review of earlier studies in E-scatter communications is made and some design considerations based on these studies are given. Results of laboratory tests made on the phase-locked loop demodulator prior to field installation of the equipment are shown and performance evaluations are made to determine the preferred, if not optimum, demodulator parameter values. Field test records from the E-scatter communications path are shown and an evaluation of system performance is made. It is concluded that 90 percent -success can be. obtained on a 915 mile E-scatter link with the receiving system studied and a transmitter output power of 320 watts. The information rate would be 10 Hz with a transmission bandwidth of about 500 Hz. Alternatively, the game success may be obtained with an extended range phase-locked loop demodulator and a transmitter output power of about 80 watts. | |
