In recent years, superresolution DOA estimation with array antenna has become indispensable for various application fields. However, the DOA estimation performance of the superresolution methods deteriorates significantly, when mutual coupling exists. Therefore array calibration is necessary. In this report, we propose a method to calibrate elevation angle dependency for DOA estimation by using additive virtual elements to the linear array. The linear array can only estimate azimuth DOA. However, the linear array can also estimate elevation DOA when real elements and virtual elements form the virtual rectangle array. The estimated calibration matrix can be regarded as a transform matrix to the virtual rectangle array. Effect of the proposed method is verified by computer simulations. |
