Geolocation of an Electromagnetic Emitter Using a Cyclostationary Time Difference of Arrival Technique

Abstract

Many applications of signal processing require that the location of an electromagnetic emitter be determined. This thesis applies an algorithm developed by Dr. William A. Gardner in 1987, that geolocates such an emitter. Special features of the algorithm not only allow the detection of cyclostationary signals in strong negative signal to noise ratio environments, but also discriminate against unwanted signals not of interest that may either occupy the same frequency band or have similar signal characteristics as the signal of interest. This is accomplished by determining spectral correlation densities for cycle frequencies equal to various exploitable features of the bpsk direct sequence spread spectrum signal....Geolocation, Cyclostationary, TDOA, Spectral correlation, Cycle frequency, BPSK, Spread spectrum.
