Abstract :
A novel algorithm of DOA estimation with unknown sensor gain and phase error is presented. There is no need of error calibration for this algorithm. The sensors´ gain and phase can be estimated after the estimation of DOA. The application of this algorithm to a linear array is also discussed. Computer simulation results illustrate that this algorithm has a good performance in medium or higher SNR for arrays with serious gain and phase errors
