RFI-Source Location

Abstract

A method to determine unknown RFI-transmitter site coordinates based on Doppler-shift measurement using the LES-8 or LES-9 satellites and previously existing pieces of ground hardware and software is described. Test cases were run to evaluate the procedure. Several RFI sources have been located. A description is given of the satellites, ground hardware, and software (as they pertain to the location technique), along with results of the site-location experiments. A second method of site location, the terminator-motion technique, is presented. It is based on a satellite rising and setting as seen from the unknown RH-transmitter site. Restrictions on this technique are discussed and results of a test case are presented. This report was originally Classified. It is being reissued with corrections of a few minor errors and misprints.
