Emitter Location Using Frequency Difference of Arrival Measurements Only [PDF]

open access: yesSensors, 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
