Emitter Location with LES-8/9 Using Differential Time-of-Arrival and Differential Doppler Shift

Abstract

Development of an emitter-location capability using differential time-of-arrival (DTOA) and different Doppler shift (DD) with the Lincoln Experimental Satellites 8 and 9 (LES-8/9) is described. Location of UHF sources over a large part of the earth can be estimated from observations as short as a few seconds by the two satellites. The principles of this emitter-location method, DTOA and DD estimation procedures, and limitations on location-estimation accuracy are discussed. Results of tests using transmissions from Lincoln Laboratory, Lexington, Massachusetts, and from a USAF transmitter at Hall Beach, Canada, demonstrate the level of accuracy achievable in practice with LES-8/9. This report was originally Classified. It is being reissued with corrections of a few minor errors and misprints.
