Frequency-unknown matched field processing for frequency estimation and localization

Matched field processing (MFP) requires prior knowledge of the frequency for the source, which is often unknown, and must be estimated from the received signals. Extending conventional MFP, incoherent frequency-unknown matched field processing (FU-MFP) is presented by incorporating the inversion of transmission frequency and radial velocity. Motion compensation of the Doppler frequency shift is achieved through the inversion of the radial velocity, thereby extending the Fourier transform window.
