A Novel Method for Estimating DOA in the Presence of Unknown Colored Noise Fields
Yun Ping Wu · Dianzi xuebao · 2001
A new method for estimating spatial narrow band signal directions of arrival in the presence of colored noise with unknown covariance is presented.An estimate of the noise covariance matrix is given.The data for parameter estimation is then prewhitened using the estimated noise covariance,hence,overcoming the highly biased estimates.Its performances are confirmed by computer simulations.
