Emitter Location Using Frequency Difference of Arrival Measurements Only [PDF]
Sensors, 2022 It is desirable to enable emitter location using frequency difference of arrival (FDoA) measurements only, since many signals are characterized by coarse range resolution and fine Doppler resolution. For instance, while using the cross-ambiguity function
