POLYSTATION DOPPLER SYSTEM

Abstract

The polystation doppler system has the ability to acquire and track a moving vehicle. The system refers to an acquisition and tracking system of more than one station which gathers only information regarding diminution or augmentation of received cycles due to motion of the vehicle relative to the station complex. The region of coverage is 800 miles long and 1000 miles high, and is limited laterally by the sides of a wedge-shaped beam. The error study which was performed for circular orbits, resulted in data which is presented in the form of graphs, some as curves and some as straightline graphs. To permit selection of optimum beamwidth, errors were studied for values from 8 to 30 degrees. In order to aid in evaluating a system after the beamwidth has been decided upon, graphs of error propagation factors were plotted holding beamwidth constant.
