Frequency domain phase-resolved optical Doppler and Doppler variance tomography [PDF]
Optics Communications, 2004 Frequency domain phase-resolved optical Doppler tomography (ODT) was developed with Doppler variance imaging capability. It is shown that utilizing the frequency domain method, phase-resolved ODT can achieve much higher imaging speed and velocity dynamic range than the time domain method.

Low-Frequency Sea Surface Radar Doppler Echo [PDF]
Remote Sensing, 2018 The sea surface normalized radar backscatter cross-section (NRCS) and Doppler velocity (DV) exhibit energy at low frequencies (LF) below the surface wave peak. These NRCS and DV variations are coherent and thus may produce a bias in the DV averaged over large footprints, which is important for interpretation of Doppler scatterometer measurements.

The Ray Theory of Doppler Frequency Shifts [PDF]
Australian Journal of Physics, 1968 A general expression is obtained according to ray theory for the Doppler frequency shift observed when both receiver and transmitter are in motion in a time-varying anisotropic but lossless medium. The result is obtained using Hamilton's optical method.
