Angle and waveform estimation in the presence of colored noise via RELAX
Jian Li, Peter Stoica, Dumin Zheng · 1995
This paper describes how the RELAX algorithm can be used for angle and waveform estimation of narrowband plane waves arriving at a uniform linear array in the presence of spatially colored noise. The RELAX algorithm is both conceptually and computationally simple; its implementation mainly requires a sequence of fast Fourier transforms. Both numerical and experimental examples are used to demonstrate the performance of the RELAX algorithm for angle and waveform estimation.
