Abstract:

A technical summary is presented of the research and development program which led to the proposal of a system for detecting and tracking nonradiating orbiting satellites. An interim research facility established the feasibility of using the doppler method and resulted in real data for which computational methods were developed which produced orbital parameters from single pass data over a single station. To meet the expected space population problem of detection and identification and to obtain a maximum range with practical emitted power, a scanned fan beam system was proposed in which a transmitter and a receiver antenna separated by about 1,000 miles would be synchronously scanned about the earth chord joining the two stations to sweep a half cylinder of space volume 1,000 miles long and having a radius of 3,000 miles.
