Robust DOA Estimation for Sources With Known Waveforms Against Doppler Shifts via Oblique Projection
TL;DR: The proposed method first transforms the nonlinear mixing of Doppler shifts in the model to an approximately linear one using discrete-time Fourier transform and finite Taylor series expansion, and has a much more robust DOA estimation performance than existing methods for sources with known waveforms.
DOA Estimation with Known Waveforms in the Presence of Unknown Time Delays and Doppler Shifts
TL;DR: A novel DOA estimation method for known waveform sources with different unknown time delays and Doppler shifts is proposed and can achieve a performance close to CRB at high SNR and with a large number of snapshots.

Superresolution 2D DOA Estimation for a Rectangular Array via Reweighted Decoupled Atomic Norm Minimization
TL;DR: This paper proposes a superresolution two-dimensional direction of arrival (DOA) estimation algorithm for a rectangular array based on the optimization of the atomic norm and a series of relaxation formulations that offers greatly improved resolution while maintaining the same computational complexity as the DAM algorithm.
A Structure-Aware DOA Estimation Method for Sources With Short Known Waveforms
TL;DR: This paper establishes the connection between DOA estimation for known waveform sources and the structured least squares (SLS) technique utilizing a potential rotation invariant property and shows that the proposed method has a better performance than the existing DEML method for small numbers of snapshots.
