RADIO INTERFER0METER ANALOG PHASE-CHANNEL COMBINER (MOD Ⅱ) FOR UNAMBIGUOUS SPACE ANGLE MEASUREMENTS IN THE NAVY SPACE SURVEILLANCE SYSTEM

摘要

The Navy Space Surveillance System, developed at the Naval Research Laboratory for the purpose of detecting nonradiating earth satellites, forms a radio fence along a great circle across the southern part of the United States. Four receiving sites alternate with three transmitting sites to form the fence. The transmitting stations illuminate satellites with radio energy as they cross the fance. The angle of arrival of the reflected signals is measured at each receiving station by a compound radio interiorometer. These signals yield a multiplicity of channels of information which are normally recorded on paper, road, and resolved. Operationally, the resolution is done by a computer, but the angle of arrival can also be resolved by using slide rules and/or tables.
