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

Frequency-difference sparse Bayesian learning for unambiguous direction-of-arrival estimation [PDF]
The frequency-difference (FD) method uses the FD Hadamard product, comprising auto-products to model below-band acoustic fields and unintended cross-products, for efficient direction-of-arrival (DOA) estimation under spatial aliasing.
