Geolocation of potential sources of Electromagnetic Interference can be accomplished through the use of the following two measurements:
________, which measures the different arrival times of the signal received over the two paths, and ________, which uses the Doppler shift to compare the change in ___________."
a) Time of arrival, Frequency modulation, Signal strength
b) Time of arrival, Doppler analysis, Signal amplitude
c) Time difference of arrival, Doppler shift, Signal frequency
d) Time difference of arrival, Frequency hopping, Signal phase
