Robust Real-Time DOA Estimation for Outdoor Vehicle Acoustic Sources Using Dynamic-Pruning GCC-PHAT and Adaptive Forgetting Factor OPAST-MUSIC

A DOA estimation method that integrates a dynamic-pruning strategy with an adaptive subspace tracking mechanism that reduces computational complexity while enhancing algorithmic stability in complex and time-varying noise environments is proposed.
